Abstract

Renormalization group arguments are used to give a complete parametrization of the disorder dependence of the mean-field superconducting Tc within a BCS model. The theory describes destruction of superconductivity in bulk materials well before the metal-insulator transition is reached, and rapid degradation of Tc in thin films with increasing sheet resistance. Comparison of explicit calculations with experiments yields good agreement.
