摘要：During the course of present investigation, an effective two-dimensional dynamic interaction potential energy function has been developed to understand the pairing mechanism leading to high-T C superconductivity in copper-oxide superconductors. The present theoretical study has been carried out under perturbation approximation using Dyson diagrammatic formalism and the technique of Fourier transforms. The effective two-dimensional dynamic interaction potential energy function obtained by us is complex in nat ure from ab -initio. The calculations of coupling strength, Coulomb repulsive parameter and transition temperature for copper-oxide superconductors consisting of one Cu-O layer per unit cell are reported here. Our calculations show that the coupling between Cu-O conducting layers makes the effective potential energy functio n more attractive as well as less rep ulsive.
