Figure 2

(a–d) Migration of small clusters and their coalescence (for example, clusters in yellow and dark blue circles merge to give crystal in green circle) over a period 1–30 min; scale bars, 2 nm. (e) The abundance of nanocrystals after 60 min. (f) Typical example of an Os crystal of ca. 1.5 nm, formed after 30 min of irradiation, scale bar, 1.5 nm. (g) Width of the clusters/crystals versus time. The error bars are the standard deviations from the mean for measurements of the width of at least 20 clusters at each timepoint. (h) Fast Fourier transform analysis of the nanocrystal shown in f.
