We have investigated the relative thermal stability of MBE-grown TiO2(100) and Nb-doped TiO2(100) surfaces grown on fully stoichiometric TiO2(100) substrates, along with the comparative interaction of Pt with these surfaces. Vacuum-annealed TiO2(100) films exhibit a well-ordered (1x3) surface reconstruction at temperature above 500'C, which is associated with parial reduction of the surface and the formation of [110]-oriented microfacets.
