Electric field-induced spin textures in a superlattice with Rashba and Dresselhaus spin-orbit coupling

Abstract

The DC charge current, field-induced spin polarization and spin textures are studied in the 1D gated superlattice with both fixed and varying Rashba and Dresselhaus contributions to spin-orbit coupling. It is found that a spin component with zero mean value can demonstrate non-vanishing field-induced spin texture in a superlattice cell which can be probed experimentally, with the highest amplitudes achievable in an interval of comparable Rashba and Dresselhaus terms. The consideration of the finite parameters for collision rate and temperature is found to be non-destructive for the calculated current and spin characteristics depending on all states below the Fermi level.
