Fig. 7

Reshaping of dendrites by surface diffusion and crystal faceting. Bottom images: growth of sharp dendrites on a large aggregate of NP. Top images: TEM imaging was then magnified to follow the reshaping of a dendrite at high resolution (time scale is reset to zero). Surface-diffusion mechanisms tend to form (111)- and (002)-type facets. These phenomena tend to enlarge the dendrite. Facet indexes are deduced from the FFT of the image acquired at t = 18 s (bottom right) showing the FCC structure of gold oriented along the [101] zone axis
