Abstract

We present a new method for equilibration of faceted nanoparticles obtained by solid state agglomeration (dewetting) of metal thin films. The method relies on crystalline defects introduced in the particles by the atomic force microscopy-based indentation and tapping. The developed method was employed for statistically based determination of the Au {1 1 1}/sapphire {0 0 0 1} interfacial energy, with the result (2.11 ± 0.08 J/m2) being in good agreement with the values reported in the literature.

    Citation Excerpt :

    The Au film becomes fully agglomerated into well separated islands after annealing for 60 min, with the islands on the edge being significantly smaller than their counterparts on the flat facets. Fully equilibrated Wulff shaped Au particles are not formed even after very long annealing for 7 days, because of the low homologous annealing temperature (0.47Tm, where Tm is the melting temperature of Au), and the defect-deficient nature of the single crystalline Au particles which impedes their equilibration [34,35]. Our experimental results on the SSD of thin Au film deposited on single crystalline KCl whisker raise questions about the physical reasons for the accelerated exposure of the whisker edges.
