adatom

From ad- +‎ atom, meaning "adsorbed atom".

adatom (plural adatoms)

1. (materials science) An atom that lies on a crystal surface

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

   • 1999, Thomas F George, Daniel A Jelski, Computational Studies Of New Materials, page 339:

     An approach to help correct this involves an adcluster, consisting of an adatom (molecule) and cluster, which is "dipped" into the electron "background" of the substrate [24,25].

   • 1987, PDMS and Clusters, page 125:

     Otherwise, in the case of pure physisorption, adatoms and very small adclusters would not be observed with the STM because the probability for the sharp eigenstates of the adparticles to lie within the 10 meV energy window ( given by the bias voltage ) would be considerably small.
