Paper Abstract

The infrared reflectivity spectra in the range from 50 to 4000cm-1 of the CdInGaS4, CdIn2S4, HgInGaS4 and CdIn2S2Se2 crystals have been investigated. The fundamental phonon parameters, the limiting dielectric constants εo and ε and the reflectivity spectrum contours have been calculated using classical dispersion relations. The values of parameters obtained from the fitting procedure are listed in the table. It is shown, that the replacement of an anion (In by Ga) leads to appearance of additional vibrational mode caused by dynamics of Ga-S molecules.
