Abstract

The critical temperature of a layered superconductor has been calculated using the model of an electron-bosonic pairing. Influence of impurities has been considered using for the bosonic propagator the modified plasmonic propagator. The main result is a decreasing of the critical temperature due to the nonmagnetic impurities. The results are important for the case of high critical temperature superconductors doped with nonmagnetic impurities.
