Electrostatic Mechanism

Electrostatic forces among stacked metal planes provide a viable mechanism for high-T c superconductivity. Dimensionless parameters which involve interplanar separations, density-of-states, and carrier density, govern the outcome. Our mechanism favors holes over electrons, and works best in layered materials. We identify regions in parameter space where superconductivity is favored, and others where charge density waves are a possible outcome. We find a distribution of superconducting energy gaps, and obtain the resulting quasiparticle density-of-states.

The current status of tunneling measurements of the superconducting density of states near the Fermi level of high-T c superconductors is reviewed. A number of the characteristics of the tunneling data that had previously been considered to be "non-ideal" follow quite naturally from conventional tunneling theory, if the effects of the unusually large energy gap, often unusually small tunneling barriers, and gap anisotropy and/or inhomogeneity are correctly accounted for. Despite formidable problems in making these measurements, due to both the very short coherence lengths and materials problems in these superconductors, a consistent body of data is emerging. A consistent picture can be drawn from this data with the aid of the new modelling presented here.
