Overlayer — An overlayer is a layer of adatoms adsorbed onto a surface, for instance onto the surface of a single crystal. Overlayers on single crystals Adsorbed layers on single crystal surfaces usually exhibit a long range order. In other words, the… … Wikipedia
Surface reconstruction — refers to the process by which atoms at the surface of a crystal assume a different structure than that of the bulk. Surface reconstructions are important in that they help in the understanding of surface chemistry for various materials,… … Wikipedia
