摘要：

The energy bands of lead and strontium sulfides in the rock-salt structure are determined using the scalar-relativistic linear-muffin-tin-orbitals method. The effect of spin-orbit coupling is discussed for the case of PbS. The results are subsequently used for the study of concentration trends in the densities of states and the Bloch spectral densities for (Pb,Sr)S mixed crystals within the coherent-potential approximation. Comparison is made with a previous study based on the empirical tight-binding model.
