WebPart of the difficulty stems from the fact that the well over 50 cuprate superconductors exhibit non-universal temperature-doping phase diagrams due to significant differences in superconducting ... WebThe cuprate superconductors share a layered crystal structure consisting of copper–oxygen planes and intervening charge reservoir layers. In a simplified picture, a copper oxide plane can be viewed as a square lattice where every site contains one hole with d x 2 –y 2 orbital character. Hole concentration can be altered by hole doping (p) or electron doping (n) …
