a, Schematic of the experimental setup. The voltage output of the pulse generator is applied through the device and both the voltage drop at the device and the pulse are monitored with an Oscilloscope with an internal impedance of 50 Ω. From these measurements, we can precisely determine the evolution of the sample resistance during the current pulse. b, Increase of the sample resistance during the application of a current pulse \(t_{{{\mathrm{p}}}} = 100\) ns (left axis). The pulse starts at time 0 ns. The colour indicates different set currents computed from the base resistance of the device \(R_0(295\;{{{\mathrm{K}}}}) = 1130\) Ω. The right axis shows the increase of temperature calculated from calibration measurements. We estimate the threshold for heat dominated motion for temperature increases of about 20 K.
