Titanium dioxide (TiO2) is one of the most technologically promising oxides with a broad
range of catalytic and photocatalytic activities. Theoretical modeling, especially density …

The direct current pulsed magnetron sputtering technology is employed to deposit TiO 2 film
onto the glass and Si (1 0 0) substrates. After annealing treatment, TiO 2 film displays …

Initial synthesis of semiconducting oxides leaves behind poorly controlled concentrations of
unwanted atomic-scale defects that influence numerous electrical, optical, and reactivity …

Isotopically pure semiconductors have important applications for cooling electronic devices
and quantum computing and sensing. Raw materials of sufficiently high isotopic purity are …

Super-band-gap illumination influences the reaction rates of semiconducting oxide surfaces
with gases and liquids, so it seems plausible that illumination also affects the analogous …

Oxygen vacancies (VO) influence many properties of ZnO in semiconductor devices, yet
synthesis methods leave behind variable and unpredictable VO concentrations. Oxygen …

Injection of interstitial atoms by specially prepared surfaces submerged in liquid water near
room temperature offers an attractive approach for post-synthesis defect manipulation and …

In the same way that gases interact with oxide semiconductor surfaces from above, point
defects interact from below. Previous experiments have described defect–surface reactions …

Low bond coordination of surface atoms facilitates the injection of oxygen interstitial atoms
into the bulk near room temperature from the clean surfaces of semiconducting metal oxides …

In this study, TiO2 coatings are deposited on Si (100) wafers by direct current pulsed
magnetron sputtering technology. The crystal structure of TiO2 coatings gradually transforms …
