In the past few years, germanium has established itself as a promising platform for spin-qubit devices. In the recent years, also its potential for the realization of hybrid devices has been revealed after the demonstration of a hard superconducting gap. Hybrid superconductor/Germanium devices could lead to the realization of minimal Kitaev chains and Andreev spin qubits. In this project, you will be involved in the realization of state of the art hybrid devices in Ge/SiGe heterostructures.  You will be fabricating  your own samples in a state of the art cleanroom. You will get familiar with cleanroom processes such as electron beam lithography, metal deposition, atomic layer deposition and perform electronic transport measurements at cryogenic temperatures.

Requirements:

Solid background in superconductivity and semiconductor physics

Some experience with nanofabrication

Passion for physics
