Lattice relaxation at a metal surface
Abstract
It is shown that all interatomic potentials of the classical type---Morse, Lennard-Jones, etc.,---yield, by their very nature, an expansion of the interlayer separation between the topmost surface layers. No such prediction can be made a priori for the oscillatory-type potentials. Using a simple procedure to compute the relaxations, we also show that Friedel's tight-binding model for transition metals yields contraction for the (100), (110), and (111) surfaces of a face-centered-cubic transition metal, a result in agreement with experiment.

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.
