Abstract

Although BCS theory completely neglects coulomb repulsion; Anderson and Morel showed very early that it plays a central role in superconductivity. Since all high TC superconductors are based on the structure of closely spaced square planner CuO2 layers and role of interlayer interaction plays important role in enhancement of TC. Therefore the present work deals with ‘Role of Coulomb repulsion in Multilayer Cuprate Superconductor’. An expression for transition temperature TC is obtained by using simple integration technique and is numerically solved. It has been found that TC decreases with electronic repulsion.
