Abstract
⺠Coarsening of Pt NPs on TiO2 is studied and simulated for three different systems. ⺠Modifications in the diffusion coalescence model: correct temperature dependence. ⺠Physically meaningful energetics for adatom formation in NPs is incorporated. ⺠More efficient simulation methods for coarsening phenomena are described. ⺠Diffusion-coalescence was found to be the dominant coarsening pathway for evaporated NPs.
