description: Topic of the final qualification work: "Effects of spatial dispersion in quantum wells". The photoluminescence and polarized reflection spectra from quantum well structures with symmetric Cd0.9Zn0.1Te/CdTe/Cd0.9Zn0.1Te and asymmetric Cd0.9Zn0.1Te/CdTe/Cd0.4Mg0.6Te barriers have been studied. The Stokes parameters of the light reflected from these structures were measured. In structures with symmetric barriers, exciton resonances were found in the reflection spectra, which do not appear in the photoluminescence spectra. In the structure with asymmetric barriers in the region of exciton resonances, the phenomenon of light birefringence caused by the reduced symmetry of the interfaces compared to the bulk of the crystal was discovered. An explanation is given for both of these phenomena. Previously, the reduced symmetry of the interface manifested itself in the photoluminescence spectra of type-2 heterostructures, where the exciton is "attached" directly to the interface. In contrast to these works, in this work, the reduced symmetry of the interface manifested itself in the dielectric response of type-1 structures near exciton resonances.
