P doped Graphane Calculations Predict Will Superconduct at 90K

Graphane is graphene with a lot of hydrogen. Graphene is two dimensional sheet of carbon. Graphane was made for the first time only last year at the University of Manchester. P-doped diamond nanowires might have similar properties. Copper oxides superconduct in an entirely different way to conventional BCS superconductors (after Bardeen, Cooper and Schrieffer, who …
