Abstract

The electronic band structures of PbS, PbSe, and PbTe have been calculated using the relativistic Green's function method. The choice of a relativistic atomic potential for Pb and of nonrelativistic atomic potentials for S, Se, and Te inthe muffin‐tin spheres results in similar band models for the lead salts. Thus a nearly uniform interpretation of experimental data for these materials can be presented. A good agreement of calculated band separations with results from reflectivity, electroreflectance, and photoemission measurements is achieved.
