Change in the Electronic Structure of Oxide Films on the Surface of a Titanium Coating in the Process of Interaction with Oxygen

In this work, the characteristic features of the morphology and electronic structure of the oxide layer of a titanium coating synthesized on the surface of highly oriented pyrolytic graphite are determined with high spatial resolution. It is found that interaction with oxygen leads to the formation of an oxide TiOx, where 1.75 < x < 2. A possibility for the synthesis of an oxide layer is shown for a specified value of the width of the band gap on the surface of a titanium coating by tailoring the duration and temperature of its annealing in oxygen.
