Post-doctoral position in Superconducting transport in topological Josephson junctions

University of Twente

A joint two years postdoctoral position between the Nanoelectronics group and the Quantum Transport in Matter group at the University of Twente is available within the TOPSQUAD FET-Open project ( The project’s research will focus on developing topologically protected states in Ge/Si core/shell nanowires by hosting pairs of Majorana fermions at opposite ends of the nanowires. Furthermore, a waferscale fabrication technology will be developed by growing thousands of nanowires through pre-patterned masks on silicon wafers, using scalable CMOS-compatible processes. This unique approach will allow topological protection in a scalable CMOS-compatible platform.
Our groups investigate supercurrents in the wires and the induced superconducting gap Δ* for different Si shell thicknesses and different electrode materials. We will study the robustness of the electrode gap as well as the proximity induced gap versus magnetic field. The proximity gap amplitude will be determined by analyzing the multiple Andreev reflections (MAR) and by conductance spectroscopy.
The candidate will work in collaboration with other members of the TOPSQUAD consortium from University of Basel, Institute of Science and Technology Austria, Basel Precision Instruments GMBH and NanoPHAB B.V.
