Vacancy-solute complexes and their clusters in iron
(ElsevierHolanda, 2020)
The role of vacancies in the mobility of dislocations and grain boundaries in magnesium
(Wiley VCH Verlag, 2007-04)
Vacancy flux or supersaturation enhances grain-boundary mobility, but experimental evidence is not large and in many cases the role of vacancies is only inferred indirectly. We will show effectively in the present work the ...
Oxygen vacancies dynamics in redox-based interfaces: Tailoring the memristive response
(IOP Publishing, 2019-09)
Redox-based memristive devices are among the alternatives for the next generation of non-volatile memories, but also candidates to emulate the behavior of synapses in neuromorphic computing de- vices. Nowadays it is well ...
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 ...
Oxygen vacancies and peroxo groups on regular and low-coordinated sites of MgO, CaO, SrO, and BaO surfaces
(Elsevier Science, 2006-03)
The formation of an oxygen vacancy and the simultaneous re-adsorption of an oxygen atom on regular and low-coordinated (LC) sites (edges and corners) of the surface of alkaline-earth oxides with cubic rock salt structure, ...
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 ...

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 ...
