Fig. 2

AFM topographs and SECM feedback maps of marked (dotted lines) MoS2 monolayer flakes with side length widths of (a, e) 3 µm; (b, f) 20 µm; (c, g) 35 µm. (Scan rate: 20 µm/s, VWE-RE (Ag): 0.6 V, Fc mediator). Color and height scales are identical for all images and the white bars indicate a distance of 5 µm. d AFM and h SECM cross-sectional height profiles along, by respectively color-encoded (green, red, and blue) arrows, indicated paths. The dotted ranges mark the extension of the islands.
