Figure 1.
(a) AC-TEM image of SVs and DVs in 2H-stacked bilayer MoS2, marked by white and red arrows, respectively. Zoomed in high-resolution transmission electron microscopy (HRTEM) image indicating (b) SVs and (c) DVs. (f, g) Multislice image simulations based on DFT-calculated atomic models with (d) one missing S atom and (e) two missing S atoms in the Mo–S–S column, respectively. The color key is SV = gray, DV = red. (h) Boxed line profiles of the SVs shown in (b) and (f). (i) Boxed line profiles of the DVs shown in (c) and (g).
