Etude de la cinétique des décharges et post-décharges excitées à hautes et très hautes fréquences dans les mélanges azotés

Adriana Annusova

Ce travail porte sur l'étude de la cinétique des décharges et post-décharges dans l'azote et les mélanges azotés en écoulement à pressions modérées. Des travaux de modélisations cinétiques ont été effectués sur la base des résultats expérimentaux afin de comprendre les processus de…

Effect of thickness and deposition rate on the structural and magnetic properties of evaporated Fe/Al thin films

M. Mebarki, A. Layadi, L. Kerkache, A. Benabbas, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

We report experimental results on the structural and magnetic properties of Fe thin films deposited by thermal evaporation onto polycrystalline Al substrates. The effect of thickness t (in the 76 to 431 nm range) and deposition rate are investigated. The texture, the strain, and the grain size…

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic…

Low work function thin film growth for high efficiency thermionic energy converter : coupled Kelvin probe and photoemission study of potassium oxide

François Morini, Emmanuel Dubois, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki

Recent researches in thermal energy harvesting have revealed the remarkable efficiency of thermionic energy converters comprising very low work function electrodes. From room temperature and above, this kind of converter could supply low power devices such as autonomous sensor networks. In this…

Geometrical optics-based model for dielectric constant and loss tangent free-space measurement

Kamel Haddadi, Tuami Lasri

A microwave free-space reflection method for determining the complex permittivity of planar dielectric materials is demonstrated. The method makes use of the measurement of the near-field microwave reflection coefficient of a metal-backed sample. The modeling of the structure and its calibration…

On detection method for soft iterative decoding in the presence of impulsive interference

Vincent Dimanche, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance improvement of soft iterative decoders in impulsive interference modeled by additive noise. In case of $alpha$-stable noise, the inputs of the belief propagation decoder are too complex to compute. We propose to use an approximation of the log likelihood ratio…

Temperature dependence of dynamic hysteresis behavior in Pb0.4Sr0.6TiO3 ferroelectric films

Kui Li, Tao Li, Gang Du, Denis Remiens, Xianlin Dong, Genshui Wang

The temperature (T) dependence of dynamic hysteresis behavior is investigated in low temperature crystallized Pb0.4Sr0.6TiO3 thin films between 85 K and 340 K. It was found that the temperature scaling relations for hysteresis area 〈A〉, remnant polarization Pr and coercive field Ec take the…

Measurement techniques for RF nanoelectronic devices : new equipment to overcome the problems of impedance and scale mismatch

Henri Happy, Kamel Haddadi, Didier Theron, Tuami Lasri, Gilles Dambrine

Scaling of electronic device dimensions into the nanoscale regime has been at the basis of the semiconductor industry for several decades. Traditional materials have been pushed to their limits, which means that entirely new materials and new device structures are now required. The development of…
