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...

Surface diffusion is a general process involving the motion of adatoms, molecules, and atomic clusters (adparticles) at solid material surfaces. The process...

growth, adatom–adatom interactions are stronger than those of the adatom with the surface, leading to the formation of three-dimensional adatom clusters...

behavior of adatoms on surfaces. The problems studied include adsorption-desorption phenomena, surface diffusion of adatoms and clusters, adatom-adatom interactions...

An overlayer is a layer of adatoms adsorbed onto a surface, for instance onto the surface of a single crystal. Adsorbed species on single crystal surfaces...

Heating of the substrate allows increased adatom–substrate and adatom–film diffusion by giving the adatoms sufficient energy to overcome kinetic barriers...

Defect types include atom vacancies, adatoms, steps, and kinks that occur most frequently at surfaces due to the finite material size causing crystal...
