| Research Abstract |
Growth of films of a TiO single-crystal, which is hard to synthesize in an atmospheric condition, has been investigated with the use of Mo(100) substrate. It was found that the epitaxial TiO film can be formed by Ti deposition on Mo(100) and subsequent oxidation of the Ti film by 12 L of O2 exposure,and the annealing of the film at higher than 1100℃. The two-dimensional band structure of a (2 ×2)TiO/Mo(100) system was investigated by angle-resolved PES, and it was found that the (2 × 2) system includes the TiO film with a (1 × 1) periodicity with respect to the Mo(100) substrate as well as the (2 ×2)-O/Mo(100) system.
