Proximity effect superconductor
WebbWe demonstrate a robust superconducting proximity effect in InAs 0.5 Sb 0.5 quantum wells grown with epitaxial Al contacts, which has important implications for mesoscopic and topological superconductivity. Unlike more commonly studied InAs and InSb semiconductors, bulk InAs 0.5 Sb 0.5 supports stronger spin–orbit coupling and a larger … Webb28 sep. 2024 · Abstract Within the Green’s function formalism, the magnetization induced by the inverse proximity effect in bilayers containing a superconductor and a strongly spin-polarized ferromagnetic metal is studied. The Usadel equations written for the dirty superconductor model are solved with boundary conditions suitable for strongly spin …
