Fig. 2. Integrated HAADF image intensity from individual (a) Pd₂₀₄₆, (b) Pd₂₆₂₂, (c) Pd₃₅₀₀, and (d) Pd₄₅₀₀ clusters as a function of their aspect ratio. Data points represent individual clusters of the respective size. The dashed lines show the average integrated HAADF intensity values for the corresponding cluster size. Histograms of cluster aspect ratios are presented in (e)–(h) for Pd₂₀₄₆, Pd₂₆₂₂, Pd₃₅₀₀, and Pd₄₅₀₀ clusters, respectively.
