a I/V traces of the junction at bias frequencies of 0.1 MHz (red) and 100 MHz (black) in the regime where the effective AC amplitude is higher than the hysteresis. \(\Delta {I}_{{{\rm{re}}}}\) and ΔIsw highlight the change in retrapping and switching currents, respectively, between the two bias frequencies. b I/V traces of the junction at bias frequencies of 8 MHz (red) and 100 MHz (black) in the regime where the effective AC amplitude is higher than the hysteresis. The mismatch in retrapping current between the red and black curves is probably due to a charge jump (note it is of the order of a few pA). c Switching and retrapping currents as a function of AC bias frequency. d–f Numerical simulations of our device in the same regime as the data shown in (a–c). The grey dashed line in (c) is a fit to the functional forms provided in equations (1)–(3).
