Why is T/sub c/ of the oxide superconductors so low

An analysis of the resistivity above T/sub c/ in the oxide superconductors shows that the inelastic-scattering rate is several times kT. This inelastic scattering yields pair breaking which suppresses T/sub c/ relative to the energy gap. The large energy scale in the problem suggests an electronic pairing mechanism, which we believe leads to d-wave pairing. The inelastic scattering has contributions from electron-phonon and from electron-electron scattering in a two-dimensional square lattice near half filling. In the latter case, the pair breaking can be reduced in a more three-dimensional structure.
