Irreversible Thermodynamics at Surfaces: Inverse Edelstein Effect for Topological Insulator

We employ Onsager’s irreversible thermodynamics (IrTh) to study the Inverse Edelstein effect (IEE) for a non-magnetic material (NM) adjacent topological insulator (TI) with strong spin-orbit interaction. The TI surface state region is treated as quasi two-dimensional (2d). For IEE, source 3d spin flux incident from NM that converts, at NM/TI interface, quasi-2d charge current in TI. Effect (EE), three-dimensional (3d) NM. coupling, considered here, when crosses 2d TI, produced along accumulation. (For weak production of and accumulation are distinct processes.) compute associated rates heating.
