CONSERVATIVE LANGEVIN DYNAMICS OF SOLID-ON-SOLID INTERFACES

We study the dynamics of an interface between two phases in interactio n with a wall in the case when the evolution is dominated by surface d iffusion. For this, we use an SOS model governed by a conservative Lan gevin equation and suitable boundary conditions. In the partial wettin g case, we study various scaling regimes and show oscillatory behavior in the relaxation of the interface toward its equilibrium shape. We a lso consider complete wetting and the structure of the precursor film.
