Figure 2
Successive clockwise propagation of atomic phason flips inside the D1 cluster at 800°C. (a)–(f) HRTEM images of the DQC taken at different times. Three ∼2 nm D clusters are marked, but we focus on the changes of the D1 cluster, as highlighted by the white outline. (g) Geometric schematic of the structural changes of D1 as time goes on. In the first row, the numbers 1, 2, …, 10 correspond to positions of possible atomic columns inside the first ∼2 nm D cluster, located on a smaller circle with a diameter of 0.77 nm. The positions occupied by atomic columns are indicated by green spots. In the middle and bottom rows, the changes of the atomic positions on the 0.77 nm D cluster are summarized. The occupied positions are indicated by solid spots and marked by numbers. The hopping of atomic columns is marked by arrows in the middle row. (h) Summary of continuous clockwise flips of atoms inside the D1 cluster. |
