Chemical reactivity of oxygen vacancies on the MgO surface: Reactions with CO2, NO2 and metals
(ELSEVIER, 2008-06)
Density functional theory was used to investigate the chemical reactivity of oxygen vacancies on the MgO surface towards CO2, NO2 and metal atoms. The oxygen vacancies induce changes in the electronic structure of the MgO ...
Influence of oxygen vacancies on the structural, dielectric, and magnetic properties of (Mn, Co) co-doped ZnO nanostructures
(Journal of Materials Science: Materials in Electronics, 2018)
Iron and oxygen vacancies at the hematite surface: Pristine case and with a chlorine adatom
(Royal Society of Chemistry, 2020-11)
Defect complexes play critical roles in the dynamics of water molecules in photoelectrochemical cell devices. For the specific case of hematite (α-Fe2O3), iron and oxygen vacancies are said to mediate the water splitting ...
Tuning the insulator-metal transition in oxide interfaces: an ab initio study exploring the role of oxygen vacancies and cation interdiffusion
(Wiley VCH Verlag, 2014-07)
We investigate the structural, electronic, and magnetic properties of a particular interface in the oxide heterostructures LaAlOmath formula/SrTiOmath formula (LAO/STO) and TiOmath formula-anatase/LaAlOmath formula (TiOmath ...
Ionized oxygen vacancy-related electrical conductivity in (Pb(1-x)La(x)) (Zr(0.90)Ti(0.10))(1-x/4)O(3) ceramics
(Iop Publishing Ltd, 2008-11-07)
The electrical conductivity behaviour in the paraelectric state has been investigated in lanthanum modified lead zirconate titanate (PLZT) ceramics, considering the universal relaxation law. The contribution of conductive ...
The role of oxygen vacancies on the microstructure development and on the electrical properties of SnO2-based varistors
(Springer, 2005-03-01)
Variations on the microstructure development and on the electrical properties of SnO2-based varistors are discussed on the basis of the oxygen vacancies created or annihilated by the presence of different additives. Electron ...
The role of oxygen vacancy in the photoluminescence property at room temperature of the CaTiO3
(American Institute of Physics (AIP), 2009-08-15)
In this paper, electron paramagnetic resonance, photoluminescence (PL) emission, and quantum mechanical calculations were used to observe and understand the structural order-disorder of CaTiO3, paying special attention to ...
