A MODEL FOR HIGH-T-C SUPERCONDUCTIVITY BASED ON CHARGE CONFINEMENT AND A POSSIBLE EXPERIMENTAL-VERIFICATION BY CHARGE KOSTERLITZ-THOULESS TRANSITION

To explain high-T-c superconductivity in a quasi-two-dimensional syste m, we proposed a charge-(electron-) confinement model, where the effec tive electron-electron interaction potential is a logarithmic function of interelectronic distance. It explains the experimentally suggested charge Kosterlitz-Thouless transition in granular films, thus possibl y verifying the model's validity.
