Abstract

Hypocharged oxygen, and not hypercharged Cu⁺³ is shown to be the generator of high-temperature superconductivity. Models based on Cu⁺²$ARLRCu⁺³ charge-fluctuations (such as t-J models), are ruled out experimentally. Experimental evidence indicates that the holes of the hypocharged oxygen in the charge-reservoir regions contribute primarily to the superconductivity,contrary to most current models of high- temperature superconductivity, which are based on superconductivity originating in the cuprate-planes. The data suggest that a successful theory of high-temperature superconductivity will be BCS-like and will pair holes through the polarization field, perhaps electronic as well as vibrational polarization.
