PhD position available: A carbon nanotube as a moving weak link

The combination of localized states within carbon nanotubes and superconducting contact materials leads to a manifold of fascinating physical phenomena and is a very active area of current research. An additional bonus is that the carbon nanotube can be suspended, i.e. the quantum dot between the contacts forms a nanomechanical system. In this research field a PhD position is immediately available; the working title of the project is "A carbon nanotube as a moving weak link".

You will develop and fabricate chip structures combining various superconductor contact materials with ultra-clean, as-grown carbon nanotubes. Together with your colleagues, you will optimize material, chip geometry, nanotube growth process, and measurement electronics. Measurements will take place in one of our ultra-low temperature setups.

Good knowledge of superconductivity is required. Certainly helpful is knowledge of semiconductor nanostructures and low temperature physics, as well as basic familiarity with Linux. The starting salary is 1/2 TV-L E13.
