Phys. Rev. B 45, 13017 (1992)] we carried out a detailed numerical analysis of the oxygen isotope effect on the La-doped Y-Ba-Cu-0 system using the excitonic-enhancement model (EEM). Following up such work, we present here another numerical analysis of the effects of oxygen deficiency on the superconductivity of the YBa2Cu307 z ceramic based on experimental data and the EEM. %'e derive also an explicit expression for the ground-state energy of a charged exciton in terms of the mass anisotropic factor a and obtain explicit expressions for the renormalized chemical potential p and energy gap functions ABcs, 5,", etc. , for the YBa2Cu307 z system. We have found that there is an inherent similarity and difference in the processes of doping and attaining oxygen deficiency. A numerical relation for a versus 6 is obtained and its justification awaits further experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
