Adatoms: An adatom is an atom that lies on a crystal surface, and can be thought of as the opposite of a surface vacancy. This term is used in surface chemistry, when describing single atoms lying on surfaces and surface roughness. The word is a contraction of "adsorbed atom". A single atom, a cluster of atoms, or a molecule or cluster of molecules may all be referred to by the general term "adparticle". This is often a thermodynamically unfavorable state. However, cases such as graphene may provide counter-examples.

Adatoms may be considered as species formed or lost during the charge transfer. Adatoms are free to move about on surface by an activated process of surface diffusion. At low current densities, electrocrystallization is thought to proceed by ...
