摘要
We have investigated the electronic structure of GaAs/AlGaAs and GaAs/AlAs quantum wells by the resonance effects of second-harmonic generation. From the energy split between the 1S and 2P exciton levels, the exciton binding energies are determined. As a result of the exciton confinement effect, a significant increase of the binding energy is found, as compared to bulk GaAs.
