Abstract
We study the energetics and stability of small Cu clusters on Cu(100) surfaces using molecular statics combined with systematic saddle-point search methods. We find several previously overlooked concerted many-particle processes that play an important role in cluster energetics. In particular, for smaller clusters there is an internal atom row shear mechanism that in some cases determines the rate-limiting step for center-of-mass motion. Our results suggest specific reaction paths for experimentally observed cluster diffusion events.Description
