Abstract
We use the Takahashi-Tachiki eigenfunction expansion of the integral equation of de Gennes to calculate the transition temperature of a metallic superlattice in the dirty limit. Application of the theory to the data of Banerjee et al. on the Nb/Cu system yields excellent agreement provided one suppresses the transition temperature of the Nb layers to correspond to that of disordered bulk Nb as discussed by Park and Geballe. It is argued that superlattices studies allow one to study thin film superconductors without the complications introduced by lower (2D) dimensionality and the associated partial breakdown of screening.
