Basic activity directions	The investigation of the influence of external actions on the physical properties of strongly anisotropic chalcogenide semiconductors and the preparation of different optoelectronic elements based on them.
Main scientific achievements	It is studied the influence of temperature and pressure on electron and phonon spectra in the strong anizotropic semiconductors of A³B⁶ and A³B³C⁶₂ groups. It is established the fact of the existence of phase transitions under pressure in layered crystals of A3B3C62 group. It is observed the new class of a ferroelectric – semiconductors with an incommensurate phase: layer crystals with structure of TlGaSe₂ type. The nature of nonconventional manifestation of thermal memory effects of an incommensurate phase in these crystals is revealed. It is shown the possibility of management by many physical properties of these crystals in the region of the existence of an incommensurate phase.
