Abstract

All layered cuprate superconductors are formed of several extended anionic complexes embedded in a cationic lattice frame. Layered anionic [CuO2]2--complexes are undispensibly present. There is a second anionic complex, varying from system to system, and doping the [CuO2]2--complex. As another generic feature, this second complex tends to quasi-onedimensional bonding. A further generic feature is the presence of ‘bridging’ oxygen mediating the doping charge transfer and causing a very strong deformation potential for the doping electron states. These features can lead to an effective interlayer coupling which is capable of producing s-channel superconductivity.
