Added row model of TiO2(110)1×2
Abstract
Scanning tunneling microscopy and first-principles atomic orbital based calculations have been used to study TiO2(110)1×2. A structure is proposed that resolves the controversy surrounding the surface morphology. Our model is simple, in that it consists only of atoms in their bulk-terminated positions. Theoretical modeling of the images shows an agreement with the experimental data that cannot be achieved even qualitatively for the previously proposed models. Furthermore, a previously unobserved 1×3 phase has been imaged that can be simply explained in terms of the model.
