Conference paper


The copper oxides provide not only a remarkably high critical temperature Tc, but also model systems for the study of this new phenomenon. The search for new materials must be guided not only by our understanding of the phenomenon itself, but also by our knowledge of the competitive mechanisms that would suppress it. The paper outlines seven competitive mechanisms to be avoided as well as a model of the normal state from which high-Tc superconductivity condenses. The model is for a polaron liquid condensing below about 300 K from a gas of correlation polarons; the correlation polarons are large and move diffusely without an activated mobility because of a vibronic resonance between distinguishable ionic and covalent Cu-O bond lengths.
