Spin-orbit and exchange proximity effects at interfaces


Abstract

We will perform first-principles and phenomenological model calculations of the electronic structure and extract relevant spin-orbit coupling and exchange fields, for various classes of interfaces: (i) semiconductor/metal, focusing on zinc-blende and wurtzite semiconductors and superconducting metals; (ii) semiconductor/ferromagnetic metal and insulator, to find proximity exchange in the semiconductors, and (iii) two-dimensional material/ferromagnetic insulator, with the goal to propose novel proximity ferromagnetic 2D semiconductors. In all cases we will map the first-principle results to effective symmetry based Hamiltonians as inputs for further model simulations.
