== '''Overview of Scanning Probe Technologies''' ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms. We work in an interdisciplinary and friendly atmosphere focused on the physics of materials at nanoscale and the micro- and nano-fabrication as well in a large scale for commercial purposes.

== '''Research''' ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with [[Kategorie:FuE3]]).

Current projects:
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|100x1500px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|100x1500px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

Radwanul.Siddique: /* Overview of Scanning Probe Technologies */

[[FuE6/English | English Version]]

[[Datei:FuE6-2013-02.jpg|thumb|right|500x500px|alt=Example alt text|From Left:[[Benutzer:Tobias.Meier | '''Tobias Meier''']],[[Benutzer:Maryna.Kavalenka | '''Dr. Maryna Kavelenka''']],[[Benutzer:Michael.Roehrig | '''Michael Röhrig''']],[[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']],[[Benutzer:Hendrik.Hoelscher | PD Dr. Hendrik Hölscher]] and [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]]]

Supervisor: [[Benutzer:Hendrik.Hoelscher | PD Dr. Hendrik Hölscher]]

== '''Overview of Scanning Probe Technologies''' ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms. We work in an interdisciplinary and friendly atmosphere focused on the physics of materials at nanoscale and the micro- and nano-fabrication as well in a large scale for commercial purposes.

== '''Research''' ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

[[Datei:2013_01_Geckos_Small8Rohrig.png|left|100x1500px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

== '''Overview of Scanning Probe Technologies''' ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms.

== '''Research''' ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

== '''Overview of Scanning Probe Technologies''' ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms.

== '''Research''' ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|120x1500px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|120x200px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

== '''Overview of Scanning Probe Technologies''' ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms.

== Research ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

== Overview of Scanning Probe Technologies ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms.

== Research ==
=== Atomic Force Microscopy ===
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

=== Nano-Tribology ===
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

=== Biomimetics ===
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Simulation and replication of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

=== Nano-Transistor ===
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|120x200px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

=== Mechanical Nano- and Micro-Resonators ===
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|120x200px|thumb|alt=Example alt text]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).

== Overview of Scanning Probe Technologies ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms.

With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.

== Overview of Scanning Probe Technologies ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies, gecko and interesting bio-inspired structures and working with very "cool" cold atoms. Within one group we work on different areas, which makes us even stronger.

== Research ==
*'''Atomic Force Microscopy:'''
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

*'''Nano-Tribology:'''
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

*'''Mechanical Nano- and Micro-Resonators:'''
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

*'''Biomimetics:'''
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and Production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Biomimetics of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

*'''Nano-Transistor:'''
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.

== Overview of Scanning Probe Technologies ==
Welcome to the Scanning Probe Technologies group!

If you are looking for a collaboration or a group to do your Doctoral studies or Bachelor/Master thesis, you are in the right place!
We are composed of physicist, mechanical and electrical engineers, having an expertise in characterization of the mechanical, physical and chemical properties of surfaces of any kinds in micro- and nano-level. We are passionate in building and modifying fancy AFM-microscopes, discovering the secrets of butterflies and gecko and working with very "cool" cold atoms. Within one group we work on different areas, which makes us even stronger.

== Research ==
*'''Atomic Force Microscopy:'''
The analysis and development of new techniques for the microscopy and spectroscopy of surfaces on the nano-scale allows new insights into the nanoworld.
:Current project: ''Cold atom scanning probe technology''
:Responsible person: [[Benutzer:Julia.Syurik | '''Dr. Julia Syurik''']]

*'''Nano-Tribology:'''
The exploration of the mechanical properties of nano-contacts and their frictional forces helps to understand the origin of friction and wear.

*'''Mechanical Nano- and Micro-Resonators:'''
Small mechanical resonators are frequently used as sensors. Due to their tiny size they sometimes reveal interesting physical effects not observable at the macro scale.
:Current project: ''TMR sensor for AFM''
:Responsible person: [[Benutzer:Tobias.Meier | '''Tobias Meier''']]

*'''Biomimetics:'''
Some animals, insects and plants show fascinating surface effects caused by their specific microscopic surface structure. We analyse these phenomena and frequently it is possible to mimic them using nano- and microreplication techniques (cooperation with FuE3).

Current projects:
:*''Rapid prototyping of Gecko adhesives and Production and analysis of functional biomimetic surfaces''
::Responsible person: [[Benutzer:Michael.Roehrig | '''Michael Röhrig''']]
:*''Biomimetics of the optical surfaces of butterfly structures''
::Responsible person: [[Benutzer:Radwanul.Siddique | '''Radwanul Hasan Siddique''']]
:*''Water harvesting technique of desert beetles''
::Responsible person: [[Benutzer:Andreas.Hoepf | '''Andreas Höpf''']]

*'''Nano-Transistor:'''
Standby switches in electronic devices are currently responsible for the loss of 6.5% of the annual electricity consumption of an average household, and this value is predicted to increase to 15% by 2030. The project goal is the development of a standby switch device with nearly zero power consumption.

=== '''Successful Replication of Hierarchical Gecko-type Structures''' ===
[[Datei:2013_01_Geckos_Small8Rohrig.png|left|thumb|alt=Example alt text|Cover page to the article: Hierarchical Structures: 3D Direct laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).]]
Due to their outstanding adhesive properties, the gecko’s toes have been extensively investigated and serve now as a prototype for the ideal adhesive tape. Their impressive attachment system enables geckos not only to adhere to nearly any surface but also to detach within milliseconds.
This famous feature is enabled by the hierarchical formation of delicate hairs covering their toes. These so-called setae, which are about 4 μm in diameter and 100 μm in length, split into the about 200 nm wide spatulae. With this hierarchical design, geckos achieve very intimate contact to flat and even to relatively rough surfaces enabling them to climb walls and ceilings only with the help of van-der-Waals interactions. Together with the Nanoscribe GmbH, we successfully introduced 3D direct laser writing (DLW) for the rapid prototyping of hierarchical gecko-inspired structures where the Young’s modulus and the relevant length scales match the gecko very closely. The obtained results show that hierarchical structures are favorable for stiff materials on the nanoscale.
The results are published in: Hierarchical Structures: 3D Direct Laser Writing of Nano- and Microstructured Hierarchical Gecko-Mimicking Surfaces, by M. Röhrig, M. Thiel, M. Worgull, and H. Hölscher in Small 19, 2918 (2012).
