The theory of the deformation influence on to dispersion law of the charge carriers in the frames of the kp-approximation for crystals with inhomogeneous bonding (chained or layered crystals) has been developed. The phonon spectra of the Cu6PS5Br-type crystals in the region of the superionic phase transition and their analogues.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
