The microscopic mechanism of high-Tc superconductors is a central problem in modern solid state physics. The overall objective of the present proposal is to develop a theoretical model for this mechanism in which Cooper pairing is mediated by plasmons. The effect on the symmetry of the order parameter of Coulomb repulsion between electrons (or holes) from different parts of the Fermi surface, will also be considered. The plasmon mechanism may also explain the significant increase in Tc and its non-monotonous dependence on dopant concentration and number of copper oxide layers in the unit cell. Studying the behaviour of Tc using the linearised gap equation and comparing theory with experimental results, could clarify the high-Tc superconducting mechanism and hence suggest ways of raising the critical temperature.High-Tc superconductivity, cuprates, pairing mechanism, plasmons, superconducting gap.
