Abstract

The spin-galvanic effect and the circular photogalvanic effect induced by terahertz radiation are applied to determine the relative strengths of Rashba and Dresselhaus band spin-splitting in (001)- grown GaAs and InAs based two dimensional electron systems. We observed that shifting the $\\delta$-doping plane from one side of the quantum well to the other results in a change of sign of ...
