Paper Abstract

In the paper, results of observations concerned Raman scattering in Zn1-xBexSe semiconductor mixed crystals are presented. Measurements of Zn1-xBexSe mixed crystals were made for temperatures 292K, 225K, 150K and 77K with Be content included in the range 0 < x < 0.25. From the polarized Raman spectra, the longitudinal optical (LO) and transverse optical (TO) modes that correspond to ZnSe-, BeSe-like single crystals, are distinguished. Theoretical calculations of the frequencies of the ZnSe-, BeSe-like modes of Zn1-xBexSe semiconductor mixed crystals were performed using MREI model (Modified Random Element Isodisplacement). Furthermore, the optical modes of Zn1-xBexSe were compared for different concentrations of Be.
