A Graphene Superconductor That Plays More than One Tune

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have discovered signs of superconductivity in three-layer sheets of graphene, renewing hope that layered graphene will soon help researchers understand how superconductivity occurs in copper oxides. That understanding could lead to higher-temperature superconductors—or even room-temperature ones—which could produce massive energy savings in electrical grids and devices.
