A model is considered that explains mechanism of non-thermal action of
microwave radiation on the thin SiO₂ (ТiO₂, Er₂O₃, Gd₂O₃) film/SiC and SiO₂/GaAs
structures. It assumes that the centers of electron-hole recombination are redistributed
because of resonance interaction between dislocations of certain length and microwave
radiation. As a result, additional bands appear in photoluminescence (PL) spectra of the
oxide film/SiC structures or intensities of some bands are redistributed in the PL spectra of
the SiO₂/GaAs structure, as well as optical density of the oxide film/SiC structures changes.
