Spin-Seebeck effect on the surface of topological insulator due to nonequilibrium spin-polarization parallel to the direction of thermally driven electronic transport

Po-Hao Chang, Farzad Mahfouzi, Naoto Nagaosa +1

We study the transverse spin-Seebeck effect (SSE) on the surface of a three-dimensional topological insulator (TI) thin film, such as Bi${}_2$Se${}_3$, which is sandwiched between two…
