a, b, Electronic transitions probed by the same metal tip apex (A = 1 Å): 0→1− (a; Vd.c. = 1.87 V, Va.c. = 1.00 Vpp, Δz = 2 Å); 1−→0 (b; Vd.c. = 1.87 V, Va.c. = 1.50 Vpp, Δz = 2 Å). Δz is given with respect to an AFM setpoint of Δf = −3.2 Hz at Vd.c. = 0 V. Scale bar, 5 Å. c, Line profiles taken along the directions indicated in a and b.
