Lj. Zou et Qq. Zheng, INVESTIGATION ON THE UNIVERSAL BEHAVIOR AND THE ORIGIN OF PAIRING IN CUPRATE AND OTHER SUPERCONDUCTORS, Physica. C, Superconductivity, 235, 1994, pp. 2101-2102
The universal dependence of high Tc superconductive transition tempera
ture on carrier density is obtained, the effects of normal-state spect
rum and pairing symmetry are discussed, a new kind of origin of pairin
g is proposed.
