Mesure de la permittivité complexe du polydimethylsiloxane (PDMS) jusqu'à 220 GHz pour la mise en oeuvre d'une électronique souple

Pierre-Yves Cresson, Yovan Orlic, Jean-François Legier, Erick Paleczny, Luc Dubois, Philippe Coquet, Nicolas Tiercelin, Sami Hage-Ali, Philippe Pernod, Vladimir Preobrazhensky, Tuami Lasri

Des lignes coplanaires sont réalisées sur un film souple de Polydimethylsiloxane (PDMS) de 182 μm d'épaisseur. Après avoir mesuré les paramètres [S] de ces lignes, des algorithmes ajustent la permittivité complexe du matériau pour que les valeurs des constantes de propagation extraites des...

Dirac cones, topological edge states, and nontrivial flat bands in two-dimensional semiconductors with a honeycomb nanogeometry

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual semiconductor properties with Dirac bands. Using atomistic tight-binding calculations, we show that both the atomic...

Contribution to testing for a correlation between ultrasonic parameters and physicochemical properties of a medium

Said Soudani, Z. Derouiche, Belal Alshaqaqi, Georges Nassar

The physicochemical parameters used to characterize the physical and chemical qualities of a medium. An ultrasonic wave through the same medium undergoes a measurable change in these parameters with its ultrasonic characteristics. The purpose of this work is to highlight the close correlation...

Conception, réalisation et test d'un micro-capteur de pression Pirani pour un fonctionnement au voisinage de la pression atmosphérique

Mohammed Moutaoukiel, Abdelkrim Talbi, Romain Viard, Jean-Claude Gerbedoen, O. Elmazria, Etienne Okada, Alain Merlen, Philippe Pernod

Cette étude concerne la conception, la réalisation et le test d'un micro-capteur de pression basé sur l'effet Pirani. La structure consiste en un fil chaud suspendu par des ponts d'oxyde de proche en proche sur des cavités de taille nanométrique. Cela permet d'obtenir une...

Improved efficiency by the effect of strain on the structure of a solar cell based on GaInP/GaAs

Abdelkader Aissat, Rachid Bestam, Jean-Pierre Vilcot

This work is aimed at the study of GaInP-based photovoltaic cell. The effects of In content, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the GaInP structure were investigated. We noticed that for higher In concentrations, the band...

Performance analysis of antenna arrays in tunnel environment

M. Lienard, C. Sanchis-Borras, J. Molina-Garcia-Pardo, D. Gaillot, Pierre Laly, Pierre Degauque

Previous works have shown that multiple-input-multiple- output techniques such as space-time block code applied to tunnel environments present better performances than a single-input-single-output transmission, despite the small angular spread of the rays in this environment. Nevertheless, taking...
