After exposing a reduced TiO 2(1 1 0) surface to an O 2 gas, the defect state seen in the band gap for the reduced surface almost disappeared, while O adatoms (O ad) appeared on the 5-fold Ti rows. We then dosed a CO gas onto the TiO 2(1 1 0) surface oxidized by 18O 2...

TiO2is a wide band gap semiconductor, one of the most extensively used transition metal oxide materials due to its various applications in, for example, light-emitting diodes1, photocatalysts2, solar cell conversion devices3, high-kgate insulators4, and waveguides5. These various applications are ...
(from an electron–hole pair orexciton) when TiO2is exposed to radiation exceeding its band gap; this radiation normally is in the UV wavelength region (290–380 nm). These electron–hole pairs are formed when an electron is elevated from the valence to the conducting band, leaving behind ...
the gap and in the case of titanium vacancy Fermi energy goes down and a defect level appears in the gap,which is about 0.4eV above the top of value band.The bond length,density of states and population of TiO2 with oxygen vacancy and titanium vacancy have also been analyzed in this ...

TiO2 has three main crystal phases: anatase, rutile and brookite. Due to the difficulties in producing pure brookite TiO2 phase [60,61], the anatase and rutile phases have been mostly studied. Even rutile TiO2 has a narrower band gap comparing with that of anatase (3.0 eV for rutile and ...
