Figure 5: Time-resolved TEM images of the oriented attachment occurred at 840 °C.
From: Direct TEM observations of growth mechanisms of two-dimensional MoS2 flakes

(a–d) Sequences of in situ TEM images indicating that flakes I and II merge into flake III; (a) 0 s, (b) 22 s, (c) 42 s and (d) 59 s. The red arrows denote the [103] direction for the adjacent flakes. Time listed for all figures is relative to the first frame. Schematic representations of the attachment stages are also included in a–d. Scale bars, 10 nm.
