Abstract
We report the imaging, mass spectrum, and dynamical behavior of adatoms and small clusters observed on the surface facets of size-selected, truncated octahedral gold clusters, Au(N) (N = 923 ± 23), via aberration-corrected scanning transmission electron microscopy. Our quantitative atom counting measurements show that most (∼70%) of the species on the surface are single Au adatoms. Such species are now proposed as key elements of the atomic structure of both monolayer-protected nanoclusters (nanoparticles) and self-assembled monolayers and may also play a role in gold nanocatalysis. The adatoms are found on both {100} and {111} facets with similar probabilities.
