Naomi Mizuno, B. Nielsen, Xu Du · Nature Communications · 2013

Summary

The fabrication of high-quality suspended monolayer graphene-NbN Josephson junctions with device mobility in excess of 150,000 cm(2) per Vs, minimum carrier density below 10(10) cm(-2), and the flow of a supercurrent at critical temperatures greater than 2 K is demonstrated.
