Semiconductor-ferromagnet-superconductor planar heterostructures for 1D topological superconductivity
Semiconductor-ferromagnet-superconductor planar heterostructures for 1D topological superconductivity
Hybrid structures of semiconducting (SM) nanowires, epitaxially grown superconductors (SC), and ferromagnetic-insulator (FI) layers have been explored experimentally and theoretically as alternative platforms for topological superconductivity at zero magnetic field. Here, we analyze a tripartite SM/FI/SC heterostructure but realized in a planar stacking geometry, where the thin FI layer acts …
