Abstract: The geometric instability of nanoscale island films is interpreted as a manifestation of the solid state wetting phenomenon, and instability of continuous extended films with nanosized thickness as a consequence of the solid state dewetting. Using molecular dynamics experiment, regularities and mechanisms are investigated of spreading of Pb solid nanoparticles on different Cu faces at a temperature 10 K below the melting temperature of nanoparticles of the chosen size (10 nm). The results obtained in molecular dynamics experiments are compared with experimental data for Pb microparticles of 5 – 10 μm in size. It has been also established that in the same «island – substrate» system both solid state wetting and solid state dewetting phenomena can simultaneously take place.

Keywords: island films, extended films with nanosized thickness, solid state wetting, solid state dewetting, molecular dynamics
