“…However, a recent scanning transmission electron microscopy study of single Pt atoms on TiO(2)(110) suggests that subsurface vacancies are more important. To clarify the role of bridging or subsurface vacancies we employ scanning tunneling microscopy to determine the bonding site of single Au atoms on TiO(2)(110). …”

“…The measurement data on contact RRAM arrays agree well with characteristics projected by the model based on the presence of randomly distributed intrinsic vacancies. A strong correlation between forming characteristics and initial states is verified, which links forming behaviors to preforming oxygen vacancies. …”

“…Electron energy loss spectroscopy was used to investigate the effect of Pr addition to CeO(2); the Ce M(5)/M(4) and O I(B)/I(C) ratios were calculated to indicate the relative changes in the Ce(3+) and oxygen vacancy concentration, respectively. There was no observable increase in the Ce(3+) concentration; however, the oxygen vacancy concentration increased with an increase in the Pr content. …”

“…TGA in air flow showed significant weight increases of up to 3.5% for reduced BaTiO(3), suggesting that metal hydride reduction yielded oxyhydrides BaTiO(3–x)H(x) with x values larger than 0.5. (1)H MAS NMR spectroscopy, however, revealed rather low concentrations of H and thus a simultaneous presence of O vacancies in reduced BaTiO(3). It has to be concluded that hydride reduction of BaTiO(3) yields complex disordered materials BaTiO(3–x)H(y)□((x–y)) with x up to 0.6 and y in a range 0.04–0.25, rather than homogeneous solid solutions BaTiO(3–x)H(x). …”
