Popis: A supercurrent can flow across the junction between two superconductors without any applied voltage. Here, the authors show how non-magnetic impurities in these so-called Josephson junctions made from graphene reduce the critical current, the maximum possible supercurrent, and skews the relationship between current and phase.
