Abstract

In the paper, results of observations concerned Raman scattering in Zn_1-xBe_xSe semiconductor mixed crystals are presented. Measurements of Zn_1-xBe_xSe 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 Zn_1-xBe_xSe semiconductor mixed crystals were performed using MREI model (Modified Random Element Isodisplacement). Furthermore, the optical modes of Zn_1-xBe_xSe were compared for different concentrations of Be.
