Quantum spin Hall phase in GeSn heterostructures on silicon
Quantum phases of solid-state electron systems can sustain exotic phenomena and a very rich spin physics. We utilize model-solid theory to show that Ge_{1−x}Sn_{x} alloys, an emerging group IV semiconductor, can be engineered into heterostructures that demonstrate a broken-gap alignment. Furthermore...
