Scanning tunnelling microscopy was used to study the (110) surface of a VC0.8 sample. The surface exhibited a missing-row reconstruction, i.e., a grating structure with ridges and valleys oriented along the [001] direction and (100) and (010) facets. No unreconstructed (110) terraces were found. The regular spacing of the ridges corresponded to a periodicity of (3 x 1) or (4 x 1), depending upon preparation, presumably related to differing concentrations of carbon vacancies. In the scanning tunnelling microscopic images, apparent pairing of atoms in the rows was also observed, leading to the larger c(6 x 2) and (4 x 2) superstructure cells, which also showed up in low-energy electron diffraction. These additional periodicities were attributed to ordering of carbon vacancies in the surface rows.Surface Structure of the Missing-Row Reconstruction of VC0.8(110) - a Scanning Tunnelling Microscopy Analysis.
