Empirical pseudopotential calculations of Cd1-xMnxTe

Empirical pseudopotential calculations for the entire range of alloy concentrations of cubic Cd1-xMnxTe are presented. The atomic form factors have been deduced empirically by fitting the band structure to spectroscopic data available from the literature. The pseudopotential band structures indicate optical bowing may occur in the alloy Cd1-xMnxTe and have been used to determine the effective masses of the electron and light, and heavy holes, which for CdTe are in agreement with accepted values. The effective masses for Cd1-xMnxTe are given for the first time, acid are expressed as first- and second-order polynomials in x. The implications of these results for spectroscopic experiments are discussed. (C) 1996 American Institute of Physics.
