a b s t r a c tIn this work we present a study of Fe self-organization on the surface of stepped MgO as a function of deposition temperature and thickness. The Fe morphology results in being very much influenced by the presence on the MgO terraces of a roughness due to exposure of the sample to the air. Because of the additional sites introduced by the MgO roughness, at room temperature Fe nucleates indistinctly on steps and terraces. Dramatic changes in the Fe nucleation appear on increasing the deposition t…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
