Abstract

AbstractIn terms of multiple scattering theory using the crystalline muffin‐tin potential and taking into account the scattering on a finite number of atoms the electronic structure of pseudobinary solid solutions NbCxN1−x is calculated for x = 1.0, 0.75, 0.5, 0.25, 0.12, and 0. A comparison with APW results is made for x = 0 and 1. It is shown, that the local partial densities of electronic states (DOS) of constituents differ from those in stoichiometric substances. The dependence of DOS at the Fermi level on carbon concentration x correlates with the dependence of superconducting transition temperature on x.
