Line Plot from Scientific Research

Zero-bias differential specific resistance versus temperature T at higher magnetic fields, measured with higher lock-in excitation voltage and more averaging than in Fig. 3a to resolve low-temperature behaviour (Supplementary Section X.B). T and its error bars are extracted using the same method as in Fig. 3a. Vertical (lower, upper) error limits are (5%, 150%) above minimum resistance, the centre value is 77.5% above minimum and the horizontal error limits are the temperatures corresponding to the (lower, upper) resistance values.
