Possible Exciton Mechanism of Superconductivity in Ag5Pb2O6/(CuO-Cu2O) Composite
Abstract
Composite material was prepared from Byström-Evers metallic particles Ag5Pb2O6 dispersed in a semiconducting matrix CuO-Cu2O. Partial substitution of CuO by Cu2O increases electric conductivity at 673 K for 2-3 orders of magnitude above Landauer conductivity e2/ha indicated by pure CuO matrix. Onset of superconductivity at 86-375 K presented in this and previous works is discussed in the framework of the exciton-polariton mechanism occurring on the grain surfaces.
