Abstract
Through density functional theory (DFT) employing two different generalized gradient approximations (GGAs), the potential energy surface (PES) describing the diffusion and vibration of CO molecules adsorbed on a Cu(100) surface, was calculated using a slab representation of the surface. Considerable effort was made to reduce the calculational error. A careful testing of all computational parameters indicates that it was possible to converge results to within ±30 meV of the DFT GGA limits for the CO/Cu(100) system.
