We present the first real-space observation of well defined single adsorbates: oxygen atoms forming the 2\ifmmode\times\else\texttimes\fi{}1 structure on Ni(110). The sawtooth model is consistent with all experimental results. The structure consists of domains, separated in the $[1\overline{1}0]$ direction by uncovered Ni ribbons 1\textonehalf{} surface unit cells wide. Such domain walls appear responsible for the $\ensuremath{\theta}=0.35$ coverage of the saturated chemisorption structure.read more
