Melting of small gold particles: Mechanism and size effects
Abstract
We present extensive molecular-dynamics simulations of small gold particles of N=100--900 atoms. We use a many-body interatomic potential of proven accuracy for gold surfaces. Structural properties are determined with various annealing strategies. Our results provide for the first time a microscopic description of the melting transition of metal clusters, revealing in particular the formation of a liquid skin as precursor effect for N>350. The experimentally observed sharp decrease of the melting temperature with decreasing size is recovered. Implications for larger sizes, as well as for other metals, are discussed.

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.
