Abstract

Raman scattering spectra in crystals of TlGaxIn1–xTe2 solid solutions are investigated, frequencies of modes of the solid solutions are determined, and the spectrum behavior character is revealed. Contributions from various atoms of the TlGaxIn1–xTe2 solid solutions to the phonon density of states are determined from first principles, phonon spectra are constructed, and frequencies of solid-solution modes are calculated.
