Graphene supercurrents go ballistic

Scientists at TU Delft and Leiden University have observed supercurrents in graphene that bounce back and forth between the edges of the graphene without scattering along the way. Supercurrents are electrical currents that flow even when there is no voltage applied. They can be induced in graphene by bringing it in contact with a superconducting material. The ability to create such ballistic superconductor-graphene hybrids makes it possible to study the unique properties of supercurrents carried by relativistic particles in an unexplored regime. These results have been published in Nature Nanotechnology.
