Abstracts

EN

The Raman spectra of TlGa_xIn_{1-x}S_2 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.
