Excitonic Superconductivity in Layer Structures
Abstract Many different theories have been presented at this Conference to try to account for the high transition temperatures, Tc, of the recently discovered copper oxide compounds. Present evidence is that the properties are consistent with a normal BCS superconductor, but with the attractive interaction that accounts for the pairing mediated by something other than phonons. Non-phonon mechanisms were suggested not long after the BCS theory was first presented. Two of the most prominent were those of Little,1 who suggested linear metallic chains surrounded by polarizable ligands, and by Ginzburg,2 who suggested a sandwich-like layer structure of metallic layers between which there are polarizable layers.
