Abstract

Graphene's supercurrent Graphene has become a model system in condensed matter physics because its charge-carrying particles move at relativistic speeds, in effect behaving as if they are massless. This leads to some peculiar electron transport properties, like the one described in this issue. In a graphene layer sandwiched between two superconducting electrodes, a superconducting current flows at low temperatures. Current is carried either by electrons or by holes, depending on the gate voltage and hence charge density in the graphene layer. Interestingly, a finite supercurrent can flow even when the charge density is zero. These observations shed light on the relativistic phenomenon known as time-reversal symmetry, and on the nature of transport mechanisms in graphene.
