Oxygen vacancies in lithium tantalate
Physical Review B, 1985Lithium tantalate crystals turn ``black'' when annealed above approximately 850 \ifmmode^\circ\else\textdegree\fi{}C in an argon atmosphere. The resulting optical absorption spectrum has a distinct peak at 460 nm but also extends through the entire visible and near ultraviolet.

The electronic properties of ZnO have traditionally been explained by invoking intrinsic defects. In particular, the frequently observed unintentional n-type conductivity has often been attributed to oxygen vacancies. We report first-principles calculations showing that the oxygen vacancy VO is not a shallow donor, but has a deep e(2+∕0) level at ∼1 ...

Oxygen Vacancy Engineering in Photocatalysis
Solar RRL, 2020Photocatalysis, which converts natural solar energy into chemical energy, has emerged as one of the most appealing technologies in the past decades. However, photocatalytic performances are limited by the poor absorption of visible light, charge‐carrier recombination during migration, and a high energy barrier for activating reactants. Oxygen vacancies

Oxygen vacancy clustering in SrTiO3-? thin films has been investigated by electrical transport and photoemission spectroscopy. We deposited SrTiO3-? thin films on LaAlO3(001) substrate at reducing oxygen ambients. The carrier density did not increase with decreasing the ambient oxygen pressure.

Abstract We present our investigations on the absorption and emission properties of the neutral oxygen vacancy in ZnO. Temperature-dependent photoluminescence (PL) experiments allow to determine the zero-phonon-energy of the emission and its phonon-coupling parameters.

Vacancy–oxygen complex in Ge crystals
Physica B: Condensed Matter, 2003Vacancy-oxygen (VO) complexes in Ge crystals have been studied by means of high-resolution infrared absorption and deep-level transient spectroscopy (Laplace DLTS) measurements. It is argued that the VO center in Ge has three charge states: double negative (VO--), single negative (VO -) and neutral (VO0) with the corresponding energy levels at E( - /-)
