Molecular-dynamics modeling of copper nanodroplet spreading on the surface of nickel

The spreading of melted copper nanodroplets on a Ni(100) crystal face has been studied by the method of molecular dynamics with a tight binding potential. The obtained kinetic curves for the radii of four bottom layers and the kinetics of dynamic contact angle well agree with the results of independent investigation [8]. The obtained equilibrium wetting angle (0.35 rad = 20$^\circ$) also agrees well with the value reported in the work cited. On the other hand, in contrast, we did not find any evidence of the formation of a precursor monolayer (i.e., of pseudopartial wetting) in the system studied.
