Orbital Mechanisms of Electron-Spin Manipulation by an Electric Field

Orbital Mechanisms of Electron-Spin Manipulation by an Electric Field

A theory of spin manipulation of quasi-two-dimensional (2D) electrons by a time-dependent gate voltage applied to a quantum well is developed. The Dresselhaus and Rashba spin-orbit coupling mechanisms are shown to be rather efficient for this purpose. The spin response to a perpendicular-to-plane electric field is due to a deviation …
