ELECTRO-OPTIC EFFECTS AND ELECTROABSORPTION IN A GaAs/AlGaAs MULTIQUANTUM-WELL HETEROSTRUCTURE NEAR THE BANDGAP
1987
We report phase difference measurements at 50 and 30 mev from the excitonic peak of a GaAs/AlGaAs multiquantum-well structure. We find pronounced dispersion of the quadratic effect; in contrast, we see no indication of dispersion in the linear effect even this close to the bandgap.
