Silicon-microtube scaffold decorated with anatase TiO2 as a negative electrode for a 3D litium-ion microbattery

Etienne Eustache, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Gilles Patriarche, David Troadec, Nathalie Rolland, Thierry Brousse, Christophe Lethien

An optimized scaffold based on silicon microtubes is designed to increase the surface capacity of 3D lithium-ion microbatteries. High-depth, mechanically robust microstructures are fabricated using microelectronic facilities. Conformal deposition of anatase TiO2 is achieved using atomic layer...

Terahertz wireless communication using GaAs transistors as detectors

L. Tohme, S. Blin, Guillaume Ducournau, P. Nouvel, D. Coquillat, S. Hisatake, T. Nagatsuma, A. Pénarier, L. Varani, W. Knap, Jean-Francois Lampin

The detection of high data-rate wireless communication using a terahertz- frequency carrier, and a GaAs transistor as a detector, is reported. Communications are investigated around 0.2 and 0.3087 THz. For the first time, an error-free transmission at data rates up to 8.2 Gbit/s is demonstrated,...

Ingénierie des matériaux artificiels électromagnétiques : cristaux photoniques et métamatériaux

D. Lippens

Le développement des techniques de micro-structuration des matériaux diélectriques et des composés métalliques permet actuellement un contrôle sans précédent de l'interaction des ondes électromagnétiques avec les matériaux artificiels. Nous illustrons ici l'ingénierie de telles structures...

Finite element analysis and experimental study of surface acoustic wave propagation through two-dimensional pillar-based surface phononic crystal

S. Yankin, Abdelkrim Talbi, Y. Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

We study both theoretically and experimentally the interaction of surface elastic waves with 2D surface phononic crystal (PnC) on a piezoelectric substrate. A rigorous analysis based on 3D finite element method is conducted to calculate the band structure of the PnC and to analyze the transmission...

Sub-THz characterisation of monolayer graphene

Ehsan Dadrasnia, Sujitha Puthukodan, Vinod V. K. Thalakkatukalathil, Horacio Lamela, Guillaume Ducournau, Jean-Francois Lampin, Frédéric Garet, Jean-Louis Coutaz

We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325-500 GHz based on fast direct measurements of phase and amplitude. We also show that these parameters can, however, be measured...
