Molecular Dynamics of Solid State Spreading in a Pb (Nanoparticle)/Cu (Substrate) System

Аннотация

The phenomenon of solid state wetting is studied via molecular dynamics (MD) in a Pb (nanoparticle)/Cu (substrate) system. It is found to be associated with capillarity-induced surface diffusion (CISD). This conclusion is confirmed by the coincidence between the MD-estimated characteristic nanoparticle spreading time and the evaluations made in the context of CISD.
