The investigations of electronic and vibrational spectra of highly anisotropic semiconductors, the influence of intertal fields on these spectra and construction on the basis of investigated crystals of new optoelectronic devices.

The electronic and vibrational spectra of highly anisotropic crystals of A³B⁶ (GaSe, TlSe etc.) and A³B³C⁶_z (TlİnS₂, TlİnSe₂ etc.) groups, the influence of temperature, pressure, high optical excitation on these spectra have been established. The physical properties of a new class of ferroelectrics-semiconductors with layer crystaline structure and transformations of these properties with temperature and pressure unduced phase non-lined optical transforme of IR radiation, high sensitive UV detectors, modulators and deflectors of optical radiation, enc have been constructed.
