Fig. 4. Aberration-corrected HADDF-STEM images of elongated Pd₁₀₀₀₀ nanoclusters. (a)–(d) Illustrate the range of aspect ratios for the cluster of the same size. (e) Reveals the local structure of one Pd₁₀₀₀₀ cluster. The arrows identify the junctions between the smaller constituent clusters. Lattice planes, and angles between them, and interplanar spacings are marked.
