abstract = {Ordered ultrathin titanium oxide films have been produced
under ultrahigh vacuum (UHV) conditions by oxidation of a
Pt3Ti(111) single crystal at elevated temperatures.
Depending on substrate temperature, oxygen dosage, and
partial pressure, four different titania phases have been
observed. All phases have been investigated by low-energy
electron diffraction (LEED) and scanning tunneling
microscopy (STM). Two commensurate phases with a rect-(6 ×
3√3) and a hex-(7 × 7)R21.8° superstructure,
respectively, are obtained at low oxygen pressures. Both
structures form homogeneous films, which wet the complete
surface and are stable against further annealing. At high
oxygen partial pressures two incommensurate structures can
be prepared. The first one contains several holes to release
stress arising from the lattice mismatch between the oxide
film and substrate. The second one shows a very rough
surface morphology and is, like the other incommensurate
phase, unstable against thermal treatment. The structures of
the different phases are very similar to the structures
found for the systems TiOx/Pt(111), VOx/Rh(111), and
VOx/Pd(111), which have been described extensively in the
literature.},
