Wave-like transmission in waveguides with spatially modulated strengths of the Rashba and Dresselhaus terms of the spin–orbit interaction

Abstract

We study electron transport through waveguides (WGs) in which the strengths of the Rashba (α) and Dresselhaus (β) terms of the spin-orbit interaction (SOI) vary in space. Subband mixing, due to lateral confinement, is taken into account only between the two first subbands.
