Study of Superconductivity Based on the Phonon-Exciton Mechanism
Abstract：Based on the phonon-exciton mechanism, the superconductivity oI yttrlum uartuLu coVVcl oxide （YBCO）system is explained. The transition temperature Tc and the oxygen isotopic coefficient βa＇ s formulae are derived by McMillan＇s energy gap function,and these expressions are reduced by using the Einstein spectrum. The theoretical analysis and caleulational results show that the superconductivity of YB3 Cu2O7-n system maybe described by phonon-exciton model.
