Autor: C. Audry, Bernard Knosp, Y. Champion, Patrick Ochin, Patrick Bernard, L. Mazerolles

Publikováno v: Journal of Alloys and Compounds. :871-874

Effects of cooling rate on microstructure and electrochemical performances of superstoichiometric AB 5 alloys with 5 wt.% Co have been investigated. Flakes of thickness ranging from 30 to 100 μm were obtained by melt spinning. The alloy microstructu

Growth of BST thin films on silicon substrates.Application to integrated capacitors for DC-DC converters

Autor: C. Mer, D. Chambonnet, C. Fages, C. Audry, Jacques Perriere, A. Fages-Bonnery

Publikováno v: Le Journal de Physique IV. :Pr9-213

Capacitor structures aiming at filtering and decoupling capacitors for DC-DC conversion, based on BST thin films, were deposited by PLD on silicon substrates. The selection of the appropriate buffer layers and of a perovskite bottom electrode allowed

Oxygen content of YBaCuO thin films

Autor: C. Audry, Jacques Perriere, A.C. Prieto, C. Belouet, J. Jiménez, D. Chambonnet, P. Martin, S. Degoy, O. Martinez

Publikováno v: Physica C: Superconductivity. 256:291-297

YBCO thin films are studied by means of Raman spectroscopy and X-ray diffraction. Data concerning oxygenation present significant dispersion as obtained from one or the other technique. This reveals structural distortion in addition to that induced b

Dependence between optical and chemical properties of Y2O3and ZrO2thin films produced by ion beam sputtering

Autor: C Hervo, C Audry, B Pointu, E Daugy

Publikováno v: Journal of Optics. 21:99-106

Thin films of yttrium oxide and zirconium oxide have been deposited by ion beam sputtering (IBS) of a Y2O3 and a ZrO2-10% Y2O3 target. It is shown that it is possible to alter the refractive index by changing the ratio between oxygen and argon flows
