A 5 nm thick Au film was deposited on single layer graphene sheets grown on Cu. By
thermal processes, the dewetting phenomenon of the Au film on the graphene was induced
so to form Au nanoparticles. The mean radius, surface-to-surface distance, and surface
density evolution of the nanoparticles on the graphene sheets as a function of the annealing
temperature were quantified by scanning electron microscopy analyses. These quantitative
data were analyzed within the classical mean-field nucleation theory so to obtain the …
