摘要：

Using a low temperature scanning tunneling microscope (STM) we have imaged isolated oxygen-related features on the unreconstructed surface between (2 x 1)-0 regions on Cu{110}. On the assumption that these are individual oxygen atoms, they appear to occupy mostly hollow sites in the troughs. We suggest that such adatoms constitute an active form of oxygen known to participate readily in deprotonation reactions on copper surfaces.
