Thespin-galvanic effect and the circular photogalvanic effect induced by terahertzradiation are applied to determine the relative strengths of Rashbaand Dresselhaus band spin splitting in (001)-grown GaAs and InAsbased two dimensional electron systems. We observed that shifting the delta -doping plane from one side of the quantum well tothe other results in a change of sign of thephotocurrent caused by Rashba spin splitting while the sign ofthe Dresselhaus term induced photocurrent remains. The measurements give thenecessary feedback for technologists looking for structures with equal Rashbaand Dresselhaus spin splittings or perfectly symmetric structures with zeroRashba constant.
