Figure 4
Successive clockwise propagation of atomic phason flips inside the D3 cluster at 800°C. (a)–(d) HRTEM images of the DQC taken at different times. Three ∼2 nm D clusters are marked, but we focus on the changes of the D3 cluster, as highlighted by the white outline. (e) Geometric schematic of the structural changes of D3 as time goes on (same presentation as in Figs. 2[link] and 3[link]). (f) This time, contrary to the cases in Figs. 2[link] and 3[link], hopping is observed in both clockwise and anticlockwise directions.
