Extended Data Fig. 5: Temperature extraction from additional circuit configurations.
a-d, circuit configurations in which additional bias-dependent (e-h) and temperature dependent (i-l) two-terminal transport measurements were carried out. m-p, comparison of traces taken at VDC = -10 mV and at base temperature with zero-bias traces taken at various temperatures. In each panel the middle value of temperature is that found to agree best with the VDC = -10 mV trace in the least-squares sense. The good agreement between the -10 mV trace and the best-fit zero-bias trace indicates that the main effect of the bias in this circuit configuration is to elevate the temperature. q-s, additional Rxx data acquired simultaneously with G2T using the circuit configuration shown in d. Estimation from Rxx gives a slightly lower temperature than G2T.
