Electric field-dependent photoexcited spin-polarized electron transport in Bi2Se3 topological insulator
Three-dimensional (3D) topological insulators (TIs) exhibit spin-polarized surface states in which the spin of electrons is locked to their momentum. The helical surface states can be explored from circularly polarized light-induced spin photocurrent, a phenomenon called circular photogalvanic effec...
