Extended Data Fig. 4: Comparing data acquired at low bias currents.

From: Direct visualization of electronic transport in a quantum anomalous Hall insulator

Extended Data Fig. 4

Same data as in Extended Data Fig. 3 but focusing on only low bias currents. Traces are color-coded and offset for clarity to indicate the back gate voltage. (a) Ia.c. = 10 nA. (b) Ia.c. = 15 nA. The VBG corresponding to the center of the QAH regime is shifted by approximately 15 V between the two data sets (see Supplementary Section 2 for details).
