Optimizing the topological properties of stacking semiconductor-ferromagnet-superconductor heterostructures

Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Michael Wimmer, , , | Summary: We study the electronic properties of a planar semiconductor-superconductor heterostructure, in which a thin ferromagnetic insulator layer lies in between and acts as a spin filtering barrier. We find that in such a system one can simultaneously enhance the […]
