Optical properties of Hg1-xMnxTe1-ySey
Abstract
Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared spectra was made by a fitting procedure based on the model of coupled oscillators. The dependence of plasma frequency and phonon modes on composition was determined. A model for phonon behavior in quaternary mixed crystals of the type A(1-x)B(x)C(1-y)D(y) was developed, too. This model was tested for Hg1-xMnxTe1-ySey. and COPY; 2004 Elsevier B.V.
