Abstract

Vicinal surfaces of Cu close to (100) are well-known to facet to (410) in the presence of chemisorbed oxygen, presumably because this produces a lower total surface energy despite the increase in surface area. The interpretation of scanning tunneling microscope images of the Cu(410)-O surface is discussed in the context of various models of this surface and previous results on the Cu(100)(square-root 2 x 2 square-root 2)R45-degrees-O phase. It appears that there are missing Cu atom rows in the middle of the (100) terraces of the Cu(410)-O structure. The favoured model for this structure optimises the opportunity for the formation of linear Cu-O Cu-O chains as found on the oxygen-reconstructed Cu(110) surface.
