摘要：

Atom-resolved images of a TiO2(110)-(1 X 1) surface were obtained by noncontact atomic force microscopy (NC-AFM) in ultrahigh vacuum. in contrast to previous scanning tunneling microscopy studies, outermost atoms of bridge-bound oxygen ridges were observed as protruding rows by NC-AFM. A high-resolution image of the surface revealed that the bridging oxygen atoms ordered in (1 X 1) periodicity on terraces. Point defects of oxygen atoms were also imaged as dark spots.
