The experimental studies of structural features of single crystals of solid solutions Cd1 – xMnxTe (х 0.032; 0.12; 0.31). are presented. The behaviour of the structural parameters of a crystal lattice on the content of the manganese component is established. Calculations of electronic energy structure and density of states of bulk solid solutions Cd1 – xMnxTe (x 0.125; 0.25; 0.375; 0.5) were studied in the framework of the density functional theory. The dependence of the band gap on the content of the manganese component in the solid solution is established. The nature of the valence and conduction bands has been identified. Significant dispersion of the electron energy spectrum was detected. As a result, the dynamics of the changes in the conductivity of electrons and holes were analyzed. |
