Abstract
Many apparently unrelated systems, including disordered metals and metallic oxides, undergo a metal/insulator transition (MIT) when their carrier concentrations are reduced and/or their disorder is increased. We have found that the superconducting transition temperature, Tc, of such materials is very often enhanced in the vicinity of the MIT. We have constructed superconductivity phase diagrams (Tc vs σ, the conductivity) for many materials whose only common feature is proximity to the MIT and found that they are remarkably similar.
Key words
