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
As a microscale tool for observing GaAs-Alx Ga1-xAs heterostructures, backscattered electron (BE) images in the scanning electron microscope (SEM) were compared with conventional secondary electron (SE) images. BE images were found to be more sensitive to compositional differences between GaAs and A
