Figure 2

(a) Low-magnification TEM image of the WSe2 membrane on grids, the dashed red rectangle highlights the folded part, scale bar, 500 nm. (b) TEM image shows the natural folded membrane without any inclusions, scale bar, 5 nm. (c) ADF image of one chiral WSe2 fold. False colour is applied, scale bar, 1 nm. (d) FFT of the image in c, which has two sets (red and blue) of spots corresponding to the up and bottom halves of the fold, scale bar, 3 nm−1. (e) Inverse FFT image for half of the WSe2 fold in c, scale bar, 1 nm. (f) Height (z) profile picture for all the W atoms in e after 3D mapping. (g) Derived 3D atomic model for half of the WSe2 fold, only W atoms shown here.
