摘要
We designed two different kinds of asymmetric quantum wells and theoretically investigated the modulation of the Rashba spin-orbit interaction by varying the internal structure inversion asymmetry of these asymmetric quantum wells in the absence of electric and magnetic fields. Our goal is to increase the strength of the Rashba spin-orbit interaction by studying the mechanism of the strength increasing of Rashba spin-orbit interaction. Designing asymmetric quantum wells structure is an effective way to control electron spin-orbit interaction. (C) 2015 Elsevier B.V. All rights reserved.
