Abstract
The electronic properties of added rows on TiO2(110) surface have been studied in real space with atomic resolution by scanning tunneling spectroscopy. It is found that no vacant Ti 3d state is observed near the Fermi level in the tunneling spectra, and accordingly the tunneling conductance is lowest at the added row sites. On the other hand, a peak of vacant states appears at 1.2 eV above the Fermi level in the spectra obtained at a hill by which an added row is terminated.Keywords
