Abstract

A new method is presented for describing the classical dynamics (e.g., diffusion, desorption) of adsorbed overlayers of atoms or molecules, starting from arbitrary interatomic potentials. Provided that a certain dynamical criterion is met, the method yields classically exact results, but with many orders of magnitude less computation than direct molecular dynamics. The approach provides, for what we believe to be the first time, a connection between stochastic lattice-gas dynamical methods and the interatomic potential function. As a sample application, the diffusion constants are computed for two-dimensional rhodium clusters of up to 75 atoms on the Rh(100) surface at T=2000 K. For clusters larger than n=15 atoms, the diffusion constant scales as ${n}^{\mathrm{\ensuremath{-}}1.76\ifmmode\pm\else\textpm\fi{}0.06}$, and the dominant mechanism for the diffusion is found to be atoms running along the edges of the cluster blocks.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
