Fig. 3: TEM characterization of monolayer MoS2 crystals with different misorientation angles.
From: Degradation behaviors and mechanisms of MoS2 crystals relevant to bioabsorbable electronics
a TEM images of the MoS2 crystals with four different angles (from 5° to 60°) suspended on Quantifoil TEM grids. b DF-TEM images of the MoS2 crystals taken at the locations marked in a. Insets are the corresponding SAED patterns. c, d HAADF-STEM images of the related MoS2 GBs, as obtained from the locations marked in b. Scale bar in d: 0.25 nm. e Schematics of the edge structure evolution between two adjacent grains when the misorientation angle increases from 5° to 60°. f The number of broken lattices per unit distance (1 nm) along the GBs gained from d
