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

Photoluminescence (PL) spectra of an MBE-grown symmetric 10 nm wide double quantum well located in the intrinsic region of a p-i-n diode were investigated in electric and magnetic ÿelds. In addition to the commonly reported spatially direct (DX) and indirect transitions, we observed in the spectra a

We calculated the exciton binding energy and energy levels in GaAs=Al0:3Ga0:7As DQWs with non-abrupt interfaces, taking into account the electric and magnetic ÿeld e ects. Numerical results for GaAs=Al0:3Ga0:7As double quantum wells show an enhancement of the e-hh exciton energy by as much as 50 meV
