Superconductor / Semiconductor hybrid nanostructures based on Germanium for quantum information

Holes in germanium have the advantage to possess a strong spin-orbit coupling enabling fast electrical control of their spin. In addition, p-type germanium has the tendency to form low-Schottky-barrier contacts with several metals, including superconducting ones. This opens the opportunity to realize novel hybrid superconductor-semiconductor devices relying on the superconducting proximity effect in germanium. The […] >>
