Abstract

The influence of the isovalent substitution of selenium for sulfur in the anion sublattice of mixed TlInS_2(1-x)Se_2x crystals has been studied by means of dielectric measurements. It is shown that transformations in the In₄(S_xSe_1-x) ₁₀ structural unit must be taken into account considering the nature of possible phase transitions in TlInS_2(1-x)Se₂ solid solutions. Possible mechanisms of the phase transition including instabilities in the electronic subsystem of pure TlInSe₂ crystals are discussed.
