We studied the Rayleigh light scattering and the optical emission in GaAs–(Al,Ga)As superlattices with ordered and intentionally disordered potential profiles, correlated and uncorrelated, in external magnetic fields. We find that the intentional disorder along z affects the resonant Rayleigh scattering and the optical emission. The external magnetic field in the same direction allows to modify the exciton localization and to study the relative modification of the light scattering and of the emission spectra.

Abstract
We studied the Rayleigh light scattering and the optical emission in GaAs–(Al,Ga)As superlattices with ordered and intentionally disordered potential profiles, correlated and uncorrelated, in external magnetic fields. We find that the intentional disorder along z affects the resonant Rayleigh scattering and the optical emission. The external magnetic field in the same direction allows to modify the exciton localization and to study the relative modification of the light scattering and of the emission spectra.File in questo prodotto:
