Abstract
The weakly incommensurate phase of monolayer krypton adsorbed on graphite has been investigated by employing the molecular-dynamics simulation technique for a 22212-krypton-atom system. The coverages and temperatures chosen correspond to the region of the phase diagram experimentally studied by Moncton et al. The simulation results are in very good agreement with the laboratory measurements. The atomic nature of the weakly incommensurate disordered phase may be described as a "domain-wall liquid."
