Direct comparison of current-induced spin polarization in topological insulator Bi2Se3 and InAs Rashba states
Abstract
Spin-polarized states arising from either Rashba splitting or topological effects are expected to produce current-induced spin polarization with different magnitude and sign. Here, Li et al. observe current-generated spin polarization in both Bi2Se3(111) and InAs (001) films, with opposite signs of the spin voltage.
