In this work we investigate the diffusion of Ag dimer on Cu(110) surface by molecular dynamics simulation based on semi-empirical many-body potentials derived from the embedded atom method. The dissociation-reassociation process is predicted to be dominant in static regime and this is confirmed by the dynamic investigation. A good agreement is found between static activation barrier and dynamic potential...
Silicene, a monolayer of silicon atoms packed into a two-dimensional honeycomb lattice is the challenging hypothetical reflection in the silicon realm of graphene, a one-atom thick graphite sheet, presently the hottest new material in condensed matter physics and nanotechnology. If existing, it would also reveal a cornucopia of new physics and potential applications. Here, we reveal the catalytic...
