Abstract

Based on the description of high-Tc cuprate superconductors as intercalation compounds and the van Hove singularity (vHs) concept for these phases, [with its consequences concerning their density of states (dos)] we give a model that explains T2 semi-quantitatively as a function of both hole concentration and stage number and, in a simplified variation, yields a functional dependence of T2 on the CuO2 layer fraction of the unit cell that shows a maximum, as observed.
