Abstract. GaAs/AlAs supelattices with corrugated interfaces have been investigated by the polarized photoluminescence method. Using the theoretical approach, which associates the linear polarization of exciton photoluminescence with the corrugation parameters, experimental results have been fitted to determine the height and lateral extension of corrugations.
Keywords: Superlattice, Corrugation, Polarization, Photoluminescence.
