Аннотация
The regularities and mechanisms of coalescence of Au nanodroplets and sintering of solid Au nanoparticles are investigated using molecular dynamics experiments and some theoretical models. It is established that the characteristic time of coalescence τ is proportional to the radius r0 of the original nanodroplets. Both the conclusion and the quantitative estimations of the proportionality coefficient between τ and r0 agree with Frenkel’s theory (1946), yet this theory was proposed for describing the coalescence of macroscopic droplets.
