DFT is used to determine the ammonia adsorption configurations at low coverage on the Pt{100}–(1×1) surface. At 0.11 and 0.22ML ammonia molecules adsorb in the on-top configuration with the N-atom binding to a surface Pt atom (α-NH 3 ). We report an ammonia dimer stable at 0.22 and 0.33ML with one molecule adsorbed in the α-state and a second one bonded via H-bond to the first molecule (β-state)...
In a previous Letter we derived analytic expressions to describe the adsorption kinetics of trimers on two-dimensional arrays. As a prerequisite to find the average saturation coverage at the jamming limit (〈θ JL 〉) we had to solve first the kinetic rate equation, which is a lengthy and troublesome task. This motivated us to derive a faster and easier procedure to determine 〈θ JL 〉...
