Helicity dependent photocurrent in electrically gated (Bi1−x Sb x )2Te3 thin films

Control of the directional photocurrent by polarized light in topological insulators may enable topological spintronics but is not yet well understood. Here the authors demonstrate that the directional photocurrent is due to the asymmetric optical transitions between topological surface states and b...
