KURBANGULOV, L.V. TSYGANKOVA, G.R. AKMANOVA, A.Kh. KUTOV This paper presents a diatomic model for describing the crystalline superionic state of copper and silver chalcogenides. A one-dimensional diatomic chain is considered where two metal atoms in series with one chalcogen atom alternate. The values of the force constants g and f were calculated for copper and silver chalcogenides with superionic properties and ordinary Cu2O and Ag2O semiconductors. Calculations showed that the interaction constants f and F are sensitive to changes in g and for superionic conductors in the nonsuperionic phase correspond the force constants g, F and f, which are smaller in magnitude than for compounds that do not have superionic properties. Key words: copper and silver chalcogenides, superionic conductors, one-dimensional diatomic model, anharmonism of vibrations. DOI: 10.25791/infizik.11.2019.1008 Contacts: - Pp. 12-16.
