## Description

- description: 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 2.7K, the junctions appear non-hysteretic with
    respect to the switching and retrapping currents IC and IR. A small non-zero resistance
    is observed even around zero bias current, and scales with temperature as dictated
    by the phase diffusion mechanism. By varying the graphene carrier concentration
    we are able to confirm that the observed phase diffusion mechanism follows the
    trend for an overdamped Josephson junction. This is in contrast with the majority
    of graphene-based junctions which are underdamped and shorted by the environment
    at high frequencies.
