Schematics of the spin current on a topological insulator surface, with the spin direction (S) perpendicular to the current direction (kx). The zoom in schematic shows the electronic band structure on the surface of the topological insulator. The spin polarization on topological insulator surface is electrically probed by a ferromagnetic tunnel contact (FM).
