Nanotechnology Now - Press Release: New study explains why superconductivity takes place in graphene: Theoretical physicists take important step in development of high temperature superconductors

Graphene, a single sheet of carbon atoms, has many extreme electrical and mechanical properties. Two years ago, researchers showed how two sheets laid on top of each other and twisted at just the right angle can become superconducting, so that the material loses its electrical resistivity. New work explains why this superconductivity happens in a surprisingly high temperature.
