Low-temperature Raman scattering in TlGaxIn1-xS2 layered mixed crystals: Compositional dependence of the mode frequencies and line shapes

The Raman spectra of TlGaxIn1-xS2 layered mixed crystals were studied for a, wide range of composition (0 <= x <= 1) at T = 50 K. The effect of crystal disorder on the line width broadening of the Raman-active modes are discussed. The asymmetry in the Raman line shape is analyzed for two interlayer and intralayer modes exhibiting one-mode behavior.
