a Differential conductance as a function of source-drain bias Vsd and gate voltage Vg for terminal pair 1 and 2 for Device 1 at B = 0 and T ~ 40 mK. b Differential conductance as a function of gate voltage for different Vsd for Device 1 at B = 0 and T ~ 40 mK. The curves correspond to Vsd values between 2.0 mV and 5.0 mV (shown by dashed black lines in a in increments of 0.125 mV, and are each offset along the Vg axis (arrow indicating direction of increasing Vsd) by 3 mV for clarity.
