Superconducting Graphene Layers

Caption

Adding calcium atoms (orange spheres) between graphene planes (blue honeycomb) creates a superconducting material called CaC6. Now a study at SLAC has shown for the first time that graphene is a key player in this superconductivity: Electrons scatter back and forth between the graphene and calcium layers, interact with natural vibrations in the material's atomic structure and pair up to conduct electricity without resistance.
