Abstract

It has been proposed that a relation exists between close packed Frank-Kasper co-ordination in the layers containing Cu-O planes and high-Tc superconductivity. The origin of the superconductivity in perovskite-type materials is attributed in part to a three dimensional nesting of the Fermi-surface with the boundary of Jones-zone, causing 'partially-gapped' Fermi surface and to a gliding charge density wave arising from a three-dimensional 'breathing' of distorted perovskite structures associated with close-packed seeking symmetry.
