英文摘要Scanning tunneling microscopy shows that a nanopattern forms as the Pt(110)-(1x2) surface is exposed to oxygen at room temperature or above. The nanopattern consists of [110] oriented O-induced stripes assembling into a (11x2) superstructure at high O coverage. The stripes form because the O adsorption energy increases by expanding the Pt lattice along the ridges of the surface as compared to the bulk. From interplay with density functional theory calculations, we show that the O-induced nanoscale periodicity is caused by short-ranged elastic relaxations confined to the surface.
