Conference paper


Switching-current distribution for supercurrent-state decay is investigated in small Josephson junctions at zero temperature. Due to resonant features of the tunneling process reflecting the existence of quantized energy levels in Josephson potential, decay to the voltage state is enhanced or suppressed by changing bias current. As a result, the switching-current distribution has peculiar peaks in a low bias regime. Resonant processes are also controlled by the sweep rate of the junction.
