For nonpolarizable systems, gold interactions were taken from the EAM parameterization in Zhou et al. For polarizable systems, parameters were taken from Bhattarai et al. From these components and parameters, four unique systems of interest were constructed: A non-polarizable fcc slab system, a polarizable fcc slab system, a system containing a 20 Å radius non-polarizable spherical nanoparticle, and a system containing another identical (but polarizable) nanoparticle.
