Helicity dependent photocurrent in electrically gated (Bi(1−x)Sb(x))(2)Te(3) thin films
Circularly polarized photons are known to generate a directional helicity-dependent photocurrent in three-dimensional topological insulators at room temperature. Surprisingly, the phenomenon is readily observed at photon energies that excite electrons to states far above the spin-momentum locked Dir...
