Raman Scattering in TlGaxIn1–xTe2 Solid Solutions: Experiment and Calculations from First Principles

Raman scattering spectra in crystals of TlGa_xIn_1–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 TlGa_xIn_1–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.
