Abstract

Rhodium grows on single-crystal Ru(0001) surface initially layer by layer, adapting the in-plane lattice parameters of Ru(0001) (pseudomorphic growth). Using quantitative low-energy electron diffraction (LEED) and density functional theory (DFT) calculations, we determined the atomic structures of 1-monolayer (ML), 2-ML, and 3-ML Rh films on Ru(0001). The 1-ML Rh film continues the hexagonal-close-packed (hcp) stacking sequence of Ru(0001) (...ABAb), while the 2-ML Rh film already adopts its face-centered-cubic (fcc) stacking sequence (...ABAbc) if the topmost Ru layer is included into the stacking consideration. Three MLs of Rh form a fcc stacking sequence of ...ABAbac, requiring a massive restructuring of the second Rh layer when adding one ML of Rh onto the 2-ML Rh film.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
