From: Capture the growth kinetics of CVD growth of two-dimensional MoS2
a–i ADF-STEM images of monolayer MoS2 with different sizes found on graphene, illuminating the shape evolution during CVD growth. A number of terraces with atomic steps can be found on the edge (arrowed, not all arrowed). j Low-mag ADF-STEM image of a triangle-shaped MoS2 monolayer, k atomic structure of the region highlighted in yellow dotted circle, l atomic structure of the local region highlighted in red dotted circle
