The spin splitting of the Al x Ga 1 À x As/GaAs/Al y Ga 1 À y As/Al x Ga 1 À x As (x a y) step quantum wells (QWs) is theoretically investigated by the method of finite difference. The Al concentration in the barrier and in the step can dramatically affect the Rashba spin splitting induced by the in
