Abstract

The thermally stable, ordered surface structures that were formed for ultrathin titanium-oxide films on a Pt(100) surface were investigated. The main focus was the morphological and structural characterization of the ordered nanostructures formed. A monolayer oxide-film structure, identified as Ti 2O3 was produced from deposited TiOx films after annealing at 750-1300 K. It was found that characterization of these oxide-film structures provides important benchmarks for theoretical calculations and a basis for understanding the chemistry of titania thin films.
