摘要：

We report on the faceting of Cu(115) surfaces upon oxygen adsorption, as studied by scanning tunnelling microscopy. For temperatures around 500 K, during or after oxygen adsorption, pronounced faceting into (104), (014) and (113) facets is observed. Details of the facet structures were analyzed. The (113) facet exhibits an additional reconstruction which can be described as a c(7 x 12) superstructure. The development of Cu-O-Cu atomic chains is suggested to be the driving force for the oxygen-induced surface reconstruction.
