The spectra of the acoustic phonons in a region of the phase transitions were studied. The electron and phonon spectra of the studied crystals were modeled. The acoustoelectric effect in Sn P S(Se) and CuInP S was investigated. A substantial enhancement of the photorefractive parameters of the Sn P S crystals was achieved and the practical schemes of their applications were tested. The peculiarities of the domain structure of the Sn P S crystals are established.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
