Basic scientific achievements:
      The presence of phase transitions was revealed and thoroughly investigated by studies of lattice temperature instability of A³B⁶ and A³B³C⁶₂ typed compounds. It was determined for the first time that phase transitions are observed with extremely structured "incommensurate" temperature regions. This also provides an opportunity to obtain complete and detailed information from the characteristics of the studied lattice dynamics. The mechanisms of the properties of the effects of gamma rays on the dielectric, optical and impedance spectra of solid solutions of TlGa_1-xIn_xSe_2(1-x)S_2x and TlGa_1-xIn_xS_e2 have been determined in a wide frequency and temperature range.
      The novelty of the research work is based on the characteristics of the hopping conductivity of solid solutions irradiated with modern research methods, current density and the Paul-Frenkel effect, characteristics of superion conductivity, impedance and optical spectra, scanning of the surface with an Atomic Force microscope. The characteristics observed in the temperature dependence of the electrical conductivity of samples of solid solution at temperatures above room temperature are related to the transition of the crystal to the superionic state in solid solutions irradiated for the first time, the dependence of the width of the straight and diagonal forbidden band on the concentration was determined from the reflection and emission spectra in the spectral range of 400-1100 nm at room temperature, as a result of the study with the Atomic Force Microscope method, the effect of radiation increases the degree of saturation of nanoscale clusters, the possibility of dissociation of molecules increases and causes the formation of critical cores. The practical significance of the research is that the obtained results can be used as suitable materials and photochromic crystals for memory elements and converters, microbatteries, supercapacitors, ionistors and gamma detectors.
