suspended CVD graphene
Roy’s paper “Phase dependent microwave response of a graphene Josephson junction” is now out. See Phys. Rev. Research 4, 013198 (2022). Roy shows that one can obtain both the resistive the resistive loss and the critical current from GHz reflectometry measurements. It is intriguing to see that the gap of a graphene Josephson weak link is virtually fully filled with Andreev bound states at phase π. This leads to a pronounced dissipation at this phase bias.
