Growth of single-crystal films of suboxides on the surfaces of refractory metals with a cubic system

用Mo(100)衬底研究了在大气条件下难以合成的二氧化钛单晶薄膜的生长。结果表明，在Mo(10 0)衬底上沉积钛，然后在12 L的氧气条件下氧化，然后在高于1 10 0℃的温度下进行热处理，可以得到外延的二氧化钛薄膜。用角分辨能谱研究了(2×2)TiO/Mo(100)系统的二维能带结构，发现(2×2)系统包括相对于Mo(100)衬底具有(1×1)周期的TiO膜和(2×2)-O/Mo(100)系统。

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.
