Early time wetting kinetics in surface-directed spinodal decomposition for off-critical quenches: A molecular dynamics study.

We present results from the molecular dynamics simulation of surface-directed spinodal decomposition in binary fluid mixtures (A + B) with off-critical compositions. The aim is to elucidate the role of composition ratio in the early time wetting kinetics under the influence of long-range surface potential. In our simulations, the attractive part of surface potential varies as V(z) = -ϵa/zn, with ϵa being the surface-potential strength.
