(a) AC-TEM image showing
the distribution of S vacancies in 3R-stacked
bilayer MoS2. The color key is SV1 = green,
DV1 = red, SV2 = gray, DV2 = purple.
Zoomed in HRTEM image indicating (b) SV1, (c) SV2, (d) DV1, and (e) DV2. (j–m) Multislice
image simulations based on DFT-calculated atomic models of a 3R-stacked
MoS2 bilayer with (f) one missing S atom and (g) two missing
S atoms in the Mo-S–S column and (h) one missing S atom and
(i) two missing S atoms in the S–S column, respectively. Vacancies
are marked as colored balls in the top view and crosses in the 3D
view. (n–q) Boxed line profiles taken along the yellow dashed
rectangles marked A–H.
