Job description

Optically Detected Magnetic Resonance (ODMR) is a spectroscopy technique that combines optical detection with magnetic resonance detection and can detect the spin of electrons and/or nucleus.

The spin spectroscopy is an important measurement tool in the field of biology, biochemistry, pharmaceutical and etc. The structure of molecules can be realized by detecting the spin polarization of electron and nucleus which gives information about the chemical bonds of the molecule and further information about the molecule.

Conventional magnetometery techniques are suffering from high signal to noise ration. One method that can reduce the noise and correspondingly increase the signal strength is to take advantage of optical detection by means of diamond impurities such as Nitrogen Vacancy centres (NV). Some impurities of diamond possess a strong photoluminescence characteristic that can be used for magnetic field detection.

The aim of this project is to develop a setup that is used for ODMR. The setup should include a confocal microscope for optical detection and additional microwave components for spin manipulation. The project is very practical and hands-on. It is desirable to have the following skills/knowledge.

  • Strong hands-on experience and instrumentation skills is required.
  • Strong General knowledge on optics is necessary.
  • Any knowledge on Quantum optics and NV centres is desirable.
