Job description

My main project is related to the new scanning probe microscopy technique, named "Cold Atom Scanning Probe Microscopy” (CA-SPM). It was recently developed at the University of Tübingen. This technique implicates the replacement of the conventional AFM tip with a gaseous ultra-cold atomic cloud. The ultra-soft probe tip is steered across the surface of interest by means of a chip-based magnetic conveyor belt. Highly precise information about the electromagnetic properties of the versatile nanostructures can be obtained by the sharply defined cloud shape and the quantum state within the cloud. The force resolution of this technique exceeds conventional AFM by several orders of magnitude, reaching the sub-yocto-newton (<10-24N) regime. The remaining fraction of atoms in the cloud (contact mode) or the changes in the centre-of-mass oscillation serve as detection signal. Yet the approaches and equations of CA-SPM are different from the conventional SPM, therefore, they are not well known within the AFM-community. The goal of the project is to analyze the equations of CA-SPM and conventional SPM in order to combine these two approaches and achieve better understanding of atomic cloud-sample interaction, alongside with characterizing properties of nanostructures with high precision.

Expertise

My expertise lies in the investigation of electro-physical and sensing properties of novel electronic devises with carbon nanostructures (CNT’s and graphene). I am experienced in design and fabrication of chemical and temperature sensors based nanocomposites with carbon nanostructures. Moreover, I am skilled in the employment of a number of characterisation techniques such as AFM, SEM and DC conductivity measurements. I am enthusiastic about this area of research and my plan for the future is to continue investigating the results of my dissertation research and provide further contribution in the field of reproducible nanopositioning of CNT’s for interconnections and nanotransistors.
