Postdoc Position

We are one of the largest and oldest universities in Europe and one of the most important employers in our region.
make us attractive for students and researchers from around the world. We offer a wide range of career opportunities in
science, technology, and administration.

The group of Professor Yoichi Ando in the Institute of Phys
- ics II of the University of Cologne is trying to elucidate the
non-Abelian nature of the Majorana zero modes generated
in a topological insulator (TI) platform and to build a Majo
- conductor hybrid devices to understand the mesoscopic
topological superconductivity realized in such a platform,
to detect and manipulate the emergent Majorana zero
modes, and to read out the results of manipulation via
charge-parity measurements.

YOUR TASKS
- Nanofabrication of nanostructured hybrid devices

combining superconductor and TI with gates
- Ultra-low-temperature experiments to understand the

proximity-induced mesoscopic superconductivity in
such devices
- Developments of the charge-parity readout technology
using quantum dots for such devices

YOUR PROFILE
You must hold a PhD degree in Experimental Solid
- State Physics or Nanoscience and must have hands-on
experience in a subset (at least 3) of the following:

- Nanofabrication of devices using electron-beam

lithography
- Ultra-low noise transport measurements
- Ultra-low temperature experiments in a dilution

refrigerator
- Time-domain microwave measurements
- Circuit QED experiments
- Experiments on TI-superconductor hybrid devices
- Quantum transport experiments in mesoscopic

systems such as quantum wires, quantum dots or
quantum Hall systems

WE OFFER
- A diverse working environment with equal

opportunities
- Support in balancing work and family life
- Extensive advanced training opportunities
- Occupational health management offers
- Flexible working time models
