Extended Data Fig. 7: Thermal activation analysis.
a, Arrhenius plot of the longitudinal resistance R at varying E (for ν = 1 and B = 0). The dashed lines show the thermal activation fit and the range of data where the fit is good. b, Extracted gap size T0 from a as a function of E near EC ≈ 11.7 mV/nm. The gap vanishes continuously as E approaches EC from above.
