Line cuts at Vtg and B ranges as marked in Fig. 3g, h, j by the respective colors at (a) Vtg = − 2.75 V, (b) Vtg = − 3.3 V, and (c) Vtg = − 3.85 V. d–i are the current density maps in arbitrary units at B marked in (a–c) by the respective symbols. The red dashed lines show the expected semi-classical trajectory.
