a–c, Forward (a) and backward (b) scans of the four-probe longitudinal resistance as a function of VTG and VBG and their difference (c). d–f, g–i, Same measurements as in a–c, except that VBG is swept between 0 V and 50 V (d–f) and between −40 V and 0 V (g–i). We present a phenomenological model to simulate the resistance maps in Supplementary Section V.3.2.
