Abstract

Using medium-energy ion-scattering (MEIS) as an in situ probe of coverage, we have investigated the adsorption of Cu on SiO2 and MgO(001) surfaces at 300 K. For the clean surfaces, only 35% (Cu/SiO2) and 50% (Cu/MgO) of the initially incident Cu atoms stick to the surfaces and are detected by MEIS. Our results are discussed in terms of a model in which desorption competes with migration and sticking of Cu adatoms onto defects and growing Cu nuclei.
