The role of oxygen vacancies and their location in the magnetic properties of Ce1-xCuxO2-delta nanorods
(Royal Soc Chemistry, 2015-01-01)
Ceria (CeO2) is a promising dilute magnetic semiconductor. Several studies report that the intrinsic and extrinsic structural defects are responsible for room temperature ferromagnetism in undoped and transition metal doped ...
The Effect of Nearest Neighbor [Pb O] Divacancy Pairs on the Ferroelectric-Relaxor Transition in Nano-Ordered Pb(Sc1/2 Nb1/2)O3
(Taylor & Francis Ltd, 2009-01)
Molecular dynamics simulations were performed on a first-principles-based effective Hamiltonians for chemically short-range ordered Pb(Sc1/2Nb1/2) O3 with nearest neighbor [Pb O] divacancy pairs. The divacancy-concentration ...
Effect of nearest neighbor Pb-O divacancy pairs on the ferroelectric-relaxor transition in Pb(Sc1/2Nb1/2)O3
(American Physical Society, 2008-12)
Molecular dynamics simulations were performed on a frst-principles-based effective Hamiltonian for Pb(Sc1/2Nb1/2)O3 (PSN) with nearest neighbor Pb-O divacancy pairs. Simulations were performed for PSN with ideal chemical ...
Oxygen related defects and vacancy clusters identified in sputtering grown UOx thin films by positron annihilation techniques
(Elsevier, 2021-08)
We experimentally studied the formation of vacancy clusters and oxygen related defects in uranium oxide (UOx) thin films (<70 nm) changing the stoichiometry in the x = 2.2?3.5 range. Films were deposited on Si(0 0 1) by ...
High-Pressure Performance of Mixed-Conducting Oxygen Electrodes: Effect of Interstitial versus Vacancy Conductivity
(Electrochemical Society, 2016-10-06)
Electrochemical response was measured as a function of oxygen pressure pO2 up to 10 bar for four different mixed-conducting oxygen electrode materials, the oxygen-vacancy-conducting perovskites (Sm0.5Sr0.5)CoO3 (SSC) and ...
Vacancies and vacancy-oxygen complexes in silicon: Positron annihilation with core electrons

Line defect Ce3+ induced Ag/CeO2/ZnO nanostructure for visible-light photocatalytic activity
(Elsevier Science SA, 2018)
This article reports, synthesis and characterization of the ternary Ag/CeO2/ZnO nanostructure which was tested for visible light photocatalytic degradation of industrial textile effluent. The HR-TEM and XPS results confirms ...
Density functional theory characterization of the formation of copper clusters on Fs and Fs+ centers on a MgO surface
(2007)
Electronic structure and chemical reactivity of Cun clusters (n = 1-4) supported on a regular site (O5c) and on an oxygen vacancy (Fs and Fs+) of the MgO (1 0 0) surface were investigated using density functional theory. ...
