Fig. 3: SECM feedback mapping of monolayer and bilayer MoS2.

From: Nanoscale redox mapping at the MoS2-liquid interface

Fig. 3

AFM topographs and SECM maps of (a, d) three complete pieces of bilayer flakes (b, e) high density of bilayer flakes on monolayer MoS2 (c, f) give a zoomed scan of the area indicated by a dashed box in b, e. Color and height scales are identical for all images and the white bars indicate a distance of 3 μm. (Scan rate: 20 µm/s, VWE-RE (Ag): 0.6 V, Fc mediator). The inset of d gives a magnified view with adjusted contrast. g–i show SECM cross-sectional profiles along the dotted arrows in images d–f.
