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.
