Ion-beam-sputtered Ta 2 O 5 /SiO 2 multi-layer stacks have been mechanically stressed to failure. The delamination failures do not occur precisely at the layer interfaces. XPS and AFM analyses indicate that the failures occur near the interfaces wher

Adsorption of chlorine on TiO2(1 1 0) surfaces modified by subsurface impurity atoms was studied by scanning tunneling microscopy. Adsorption was found to be suppressed in the vicinity of positively charged subsurface donor atoms. The reduced adsorpt

The adsorption of molecular sulfur on TiO 2 (1 1 0)(1×1) has been studied with scanning tunneling microscopy and photoelectron spectroscopy. At room temperature S binds dissociatively to 5-fold coordinated Ti atoms and oxygen vacancies. At elevated

The temperature dependent adsorption of sulfur on TiO2(1 1 0) has been studied with X-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and low-energy electron diffraction (LEED). Sulfur adsorbs dissociatively at room tempera

We report scanning tunneling microscopy and complementary spectroscopic measurements on TiO 2(110) surfaces. We show data on (i) a surface restructuring process that results from annealing in oxygen; (ii) Pt clusters, grown at room temperature and en

We have studied the adsorption of elemental sulfur on TiO 2 (110) for exposure at room temperature and at 300°C. Depending on the substrate temperature we found diVerent adsorption sites with scanning tunneling microscopy (STM ). At room temperature

The authors have investigated the relationship between different types and amounts of bulk defects and the surface morphology of TiO{sub 2}(110) single crystals prepared by annealing in ultrahigh vacuum and in oxygen. Rutile TiO{sub 2}(110) specimens

Nanosized platinum clusters were grown on a TiO2(110) surface and annealed in ultrahigh vacuum at high temperatures. This leads to the so-called strong metal-support interaction (SMSI) state, characterized by a complete encapsulation of the clusters

When reduced ${\mathrm{TiO}}_{2}(110)$ single crystals are oxidized at moderate temperatures (470--660 K), the surfaces restructure. Interstitial Ti atoms from the bulk diffuse to the surface where they react with gaseous oxygen and form new, added $

We report a comprehensive experimental and theoretical study of the eVect of oxidizing a TiO 2 (110) surface at moderate temperatures. The surfaces are investigated with scanning tunneling microscopy (STM ), low-energy He+ ion scattering (LEIS ) and
