摘要：

The surface reconstruction of the W(001) surface in the presence of oxygen has been studied by scanning tunneling microscopy. A two-domain (2 x 1) structure with domain size approximately 30 angstrom was observed after the oxygen-covered surface was annealed at > 1000-degrees-C for < 1 min. Tunneling microscopy and spectroscopy results support the missing-row model for the (2 x 1) structure; the preferred location for adsorbed oxygen is either the threefold-hollow site or a site on top of a W atom in the second layer.
