摘要：

Density-functional calculations for a wide variety of metals show that, contrary to rebonding theory, ad-dimers do not have notably longer surface bonds than adatoms, do not reside farther above the surface, and do not meet the rebonding arguments for augmented mobility. Rebonding contributes to destabilize ad-dimers, but does not explain inherently weak ad-dimer bonds.
