An atom that lies on a crystal surface

We studied silicon adatoms on the Si(100) surface.

(Kimya) 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, 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

(Kimya) (Physical Chemistry) An atom adsorbed on a surface
