- 1. Phys. Rev. B 75, 144102 (2007) , “Theoretical investigation of nitrogen substitution in cubic zirconia”, Thomas BredowNitrogen substitution of oxygen ions in cubic zirconia was studied theoretically at density functional level. Nitrogen contents of 12.5 and 3.1% were studied with Zr8O16−mN2 and Zr32O64−mN2 supercells. For... (Read more)
- 2. Appl. Phys. Lett. 89, 202904 (2006) , “Effects of O vacancies and C doping on dielectric properties of ZrO2: A first-principles study”, Gargi Dutta, K. P. S. S. Hembram, G. Mohan Rao, and Umesh V. WaghmareThe authors determine electronic properties, structural stability, and dielectric response of zirconia (ZrO2) with oxygen vacancies (O vacancies) and carbon doping (C doping) using first-principles density functional theory calculations based on pseudopotentials and a plane wave basis....

- 3. J. Appl. Phys. 99, 123501 (2006) , “Thermal annealing study of swift heavy-ion irradiated zirconia”, Jean-Marc Costantini, Andrée Kahn-Harari, François Beuneu, and François CouvreurSintered samples of monoclinic zirconia (-ZrO2) have been irradiated at room temperature with 6.0 GeV Pb ions in the electronic slowing down regime. X-ray diffraction (XRD) and micro-Raman spectroscopy measurements showed unambiguously that a transition to the "metastable"... (Read more)
- 4. Phys. Rev. B 74, 132107 (2006) , “Evidence of extended defects in pure zirconia irradiated by swift heavy ions”, Gianguido Baldinozzi, David Simeone, Dominique Gosset, Isabelle Monnet, Sophie Le Caër, and Léo MazerollesX-ray diffraction, transmission electron microscopy, and optical spectroscopy were used to investigate the microstructure of polycrystalline samples of pure monoclinic zirconia irradiated by high energy ions. These techniques point out the existence of extended defects and they allow to monitor the... (Read more)
- 5. Appl. Phys. Lett. 80, 1261-1263 (2002) , “Hole trapping in ultrathin Al2O3 and ZrO2 insulators on silicon”, V. V. Afanas'ev and A. StesmansOptical injection of electron-hole pairs in 35 nm thick layers of SiO2, Al2O3, ZrO2 and their stacks on (100)Si is found to result in positive oxide charging, suggesting trapping of holes. In thin layers of the high-permittivity metal oxides... (Read more)
- 6. Radiat. Meas. 26, 131-137 (1996) , “Effect of oxide additives on radiolytic decomposition of zirconium and thorium nitrates”, N. G. Joshi, A. N. Garg, V. Natarajan and M. D. SastryGamma ray-induced decomposition of the binary mixtures of zirconium and thorium nitrates with 2.5, 5 and 10 mol% of V2O5, PbO, ThO2, ZrO2, and MnO2 has been studied at different doses up to 260 kGy. Radiation chemical yield G(NO2−)-values are enhanced by V2O5, PbO, and ThO2 but are decreased... (Read more)
