Nanocrystalline Cubic Phase Scandium-Stabilized Zirconia Thin Films [PDF]

open access: goldNanomaterials
The cubic zirconia (ZrO2) is attractive for a broad range of applications. However, at room temperature, the cubic phase needs to be stabilized. The most studied stabilization method is the addition of the oxides of trivalent metals, such as Sc2O3 ...

Thermodynamic stability of oxygen point defects in cubic Zirconia [PDF]

open access: greenarXiv, 2010
Zirconia (ZrO2) is an important material with technological applications which are affected by point defect physics. Ab-initio calculations are performed to understand the structural and electronic properties of oxygen vacancies and interstitials in different charge states in cubic zirconia.

Thermal recovery of colour centres induced in cubic yttria-stabilized zirconia by charged particle irradiations [PDF]

open access: greenJournal of Physics: Condensed Matter 18 (2006) 3671, 2006
We have used electron paramagnetic resonance to study the thermal annealing of colour centres induced in cubic yttria-stabilized zirconia by swift electron and heavy ion-irradiations. Single crystals were irradiated with 1 or 2-MeV electrons, and 200-MeV 127I, or 200-MeV 197Au ions. Electron and ion beams produce the same colour centres: namely i) an F+
