Germanium/Silicon Nanowire Heterostructures for Quantum Computing

Nanowires and their synthesis have gained increasing interest as nanosized building blocks for functional devices, due to their tuneable and fascinating properties. The compatibility of silicon and germanium with complementary metal oxide semiconductor technology makes them highly attractive. Combining the two materials to germanium-silicon core-shell nanowires provides optimal candidates for quantum applications due to their outstanding characteristics of absent nuclear spin, long coherence times, high spin-orbit coupling, strong confinement of holes, high carrier mobility of germanium at room temperature and high quality silicon dioxide. To foster these properties, high quality nanowires are needed. Chemical vapour deposition techniques provide the necessary control over the dimension, the crystal phase, and the crystallographic orientation. [...]
