Electron transfer of local pairs in crystals and superconductivity of metal oxide compounds
Abstract
Hybridization of two-electron centers (local pairs) and conduction electrons in crystals results in universal interaction between the pairs. This mechanism leads to the transfer of pairs between their localized positions even when the wave functions do not directly overlap. The transition to an ordered state is of the superconducting glass type. If the energy level of the pairs (converted to a single electron) is located above the Fermi level or lies in the forbidden band near the filled state boundary, the mechanism of 'return' superconductivity becomes possible.
