Your Task

Two dimensional hole gases like in strained Germanium have shown recent promise in gated electronics, both with the superconducting and spin community. With the low effective mass, high carrier mobility, spin-orbit coupling, and fermi-level pinning, we open a new toolbox of experiments to be done with proximitized planar Josephson junctions with Germanium. Depending on the properties of the hole gas, we can study exotic versions of existing junction phenomena and try to understand the physics behind few-mode superconducting transport. Through this project, we aim to optimize junction characterization at milli-Kelvin temperatures and gain insight on the effects of junction geometry on the physics of Andreev Bound States in nanoscale devices.

Required Skills

To be part of this project, you must have basic theoretical understanding of superconductivity and quantum transport. You must be able to work in a small team and collaborate with students working on diverse projects with the same setup. Given that all of the measurements that we do are code-based, we require you to have experience with Python and object oriented programming.

What we offer

  • Workplace, laptop for duration of the project.
  • Student assistant contract via RWTH, or equivalent via FZ Jülich contract
  • Young, international, dynamical workplace, located on Campus Melaten (Campus- Boulevard 79)
  • Exposure to leading research activities in quantum technology
