Abstract

We derive the expressions for the transition temperature Tc, and the spatial dependence of the superconducting gap for a multilayer high-Tc superconductor composed of groups of tightly spaced planes separated by a larger distance. The results are compared with experiment and provide strong support for an interlayer hopping as the driving force of the large Tc enhancement in multilayered compounds. Our results are universal in the sense that they are valid for an arbitrary pairing potential Vkk′ in the CuO2 planes, as well as for both Fermi- and non-Fermi-liquids.
