Overdamped phase diffusion in hBN encapsulated graphene Josephson junctions
We investigate the zero-bias behavior of Josephson junctions made of encapsulated graphene boron nitride heterostructures in the long ballistic junction regime. For temperatures down to 2.7 K, the junctions appear nonhysteretic with respect to the switching and retrapping currents I_{C} and I_{R}. A...
