Figure 1: SAED patterns evolved with growth temperature.
From: Direct TEM observations of growth mechanisms of two-dimensional MoS2 flakes

(a) Schematic side view of the experimental set-up of in situ TEM heating stage. (b–e) The evolution of SAED patterns across a wide temperature range: (b) 25 °C, (c) 400 °C, (d) 780 °C and (e) 900 °C. Scale bars, 5 nm−1.
