Environment-induced overheating phenomena in Au-nanowire based Josephson junctions

Abstract Unlike conventional planar Josephson junctions, nanowire-based devices have a bridge geometry with a peculiar coupling to environment that can favor non-equilibrium electronic phenomena. Here we measure the influence of the electron bath overheating on critical current of several bridge-lik...
