摘要：

Far-infrared reflection and Raman spectra of Hg1-xMnxSe (x <= 0.3) alloys were measured at room temperature. The analysis of the Raman spectra was made by deconvolution technique. The analysis of the far-infrared spectra was made by a fitting procedure based on dielectric function which includes spacious distribution of free carrier influence on the plasmon-phonon interaction. In spite of strong plasmon-LO phonon interaction, we found that the long wavelength optical phonon modes of these mixed crystals showed two-mode behaviour. The model of phonon behaviour was developed, and we obtain very good agreement with experimental results. (C) 2008 Elsevier B.V. All rights reserved.
