Physical factors affecting Rashba Spin-orbit coupling

ORAL

Abstract

The Rashba Spin-orbital coupling plays a crucial role in charge and spin transport in semiconductor heterostructure. We study several physical parameters which may contribute to Rashba Spin-orbital coupling, including asymmetric potential barriers, quantum well inclination, effective mass, and band mixing. This may provide some insights in designing spintronic microdevices .
