Figure 3.1. Coalescence-induced crystallisation of amorphous Palladium nanoparticles. (a) Final configurations after 100 ps molecular dynamics run of two amorphous nanoparticles coalescing at various temperatures. Emerging facets of specific crystallographic planes are denoted for the 300 and 1000 K configurations, which are enlarged at (b) and (c), respectively. Epitaxial atomic arrangement and formation of twinned crystallites is clear in both cases. (For clarity, temperatures are represented by shades of colours).
