Figure 4: High-resolution (S) TEM images for various folded structures.

From: Two-dimensional membrane as elastic shell with proof on the folds revealed by three-dimensional atomic mapping

Figure 4

(a) ADF image for one armchair WSe2 fold, scale bar, 1 nm. (b) Atomic model for a. (c) The cracked WSe2 fold (strain released), which has a nearly perfect AB stacking order between the up and bottom layers, scale bar, 1 nm. (d) Atomic model for c. (e,f) Original (e) and separated half ADF images (f) for one chiral MoS2 fold, similar to Fig. 2c,d, scale bars, 1 nm. (g,h) The HRTEM images for zigzag (g) and chiral (h) monolayer graphene folds, scale bars, 1 nm. (i) Low-magnification TEM image for WS2 vertical fold, model shown in inset, scale bar, 100 nm. (j,k) High-resolution ADF images for the vertical fold, the membrane has some rippling so the left (j) and right part (k) are not on the same height and cannot be focused in the same time thus are presented in two panels, scale bars, 1 nm.
