Conception d'un réseau de capteurs acoustiques passifs pour un contrôle-santé intégré basse consommation et non-intrusif des structures aéronautiques et conduites de transport de fluides

Karl Hourany, Farouk Benmeddour, Emmanuel Moulin, Youssef Zaatar, Jamal Assaad

La corrélation d'un champ acoustique permet de caractériser un milieu de façon passive, cette étude a commencé à se développer depuis plusieurs années dans différentes applications de contrôle santé intégré (CSI). Une brève explication d'une étude faite précédemment pour la détection des...

A real-time terahertz beam monitoring application with a 1024-pixel CMOS terahertz camera module

Richard Al Hadi, Jean-Francois Lampin, Ullrich Pfeiffer

In this paper a terahertz beam monitoring application of an optically pumped molecular terahertz laser with a 1024-pixel CMOS terahertz camera is presented. The terahertz camera has been used to detect variations in real-time of the terahertz source beam around 2.52 THz.

Angle-dependent ray tracing simulations of reflections on pyramidal textures for silicon solar cells

Vincent Magnin, Joseph Harari, Mathieu Halbwax, S Bastide, D Cherfi, Jean-Pierre Vilcot

Pyramidal textures are commonly used to reduce reflections from silicon solar cells and improve light absorption by light trapping. They are generally modelled or characterized under normal incidence. In this work, a monolayer 3D ray tracing program taking into account the polarisation of light...

Multi-phonon scattering processes in one-dimensional anharmonic biological superlattices : understanding the dissipation of mechanical waves in mineralized tissues

Pierre-Yves Guerder, Alix C. Deymier-Black, Nichlas Z. Swinteck, Jerome O. Vasseur, Olivier Bou Matar, Krishna Muralidharan, Pierre A. Deymier

The scattering of elastic waves in a one dimensional phononic (PnC) crystal composed of alternate collagen and hydroxy-apatite constituent layers is studied. These superlattices are metaphors for mineralized tissues present in bones and teeth. The collagen is treated as an open system elastic...

Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

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

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator...

Effect of polarization switching cycles on the dielectric response and Rayleigh constant in Pb0.4Sr0.6TiO3 thin films

Kui Li, Xianlin Dong, Denis R Émiens, Tao Li, Ying Chen, Genshui Wang

Pb0.4Sr0.6TiO3 thin films with good fatigue endurance were crystallized at low temperature compatible with the current semiconductor technology. The effect of polarization switching cycles on the ferroelectric properties, dielectric response, and Rayleigh constant in thin films were systematically...

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances...

Optimized V-shape design of GaN nanodiodes for the generation of Gunn oscillations

J.F. Millithaler, I. Iniguez-De-La-Torre, A. Iniguez-De-La-Torre, T. Gonz Alez, P. Sangaré, Guillaume Ducournau, Christophe Gaquière, J. Mateos

In this work, recent advances in the design of GaN planar Gunn diodes with asymmetric shape, socalled self-switching diodes, are presented. A particular geometry for the nanodiode is proposed, referred as V-shape, where the width of the channel is intentionally increased as approaching the anode....
