AlN/IDT/AlN/Sapphire SAW Heterostructure for High-Temperature Applications

Ouarda Legrani, Thierry Aubert, Omar Elmazria, Ausrine Bartasyte, Pascal Nicolay, Abdelkrim Talbi, Pascal Boulet, Jaafar Ghanbaja, Denis Mangin

Recent studies have evidenced that Pt/AlN/Sapphire SAW devices are promising for high-temperature high-frequency applications. However, they cannot be used above 700°C in air atmosphere as the Pt interdigital transducers (IDTs) agglomerate and the AlN layer oxidizes in such conditions. In this...

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user...

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to...

Broadband dielectric characterization of aqueous saline solutions by an interferometer-based microwave microscope

S. Gu, Tianjun Lin, T. Lasri

The complex dielectric permittivity of aqueous saline solutions has been determined in the frequency range [2-18 GHz] with a home-made near-field microwave microscope. The instrument is built on a vector network analyzer, a matching network, and an evanescent microwave probe. The interferometer-...

Mode-hopping suppression in long Brillouin fiber laser with non-resonant pumping

Gwennaël Danion, Ludovic Frein, Denis Bacquet, Grégoire Pillet, Stéphanie Molin, Loïc Morvan, Guillaume Ducournau, Marc Vallet, Pascal Szriftgiser, Mehdi Alouini

We propose a reliable method for stabilizing narrow linewidth Brillouin fiber lasers with non-resonant pumping. Mode-hopping is suppressed by means of a phase-locked loop that locks the pump-Stokes detuning to a local radio-frequency (RF) oscillator. Stable single-mode operation of a 110-m-long...

Investigation of the Effect of Plasma Polymerized Siloxane Coating for Enzyme Immobilization and Microfluidic Device Conception

Kalim Belhacene, Adil Elagli, Céline Vivien, A. Treizebre, Pascal Dhulster, Philippe Supiot, Renato Froidevaux

This paper describes the impact of a physical immobilization methodology, using plasma polymerized 1,1,3,3, tetramethyldisiloxane, on the catalytic performance of β-galactosidase from Aspergillus oryzae in a microfluidic device. The β-galactosidase was immobilized by a polymer coating grown by...

Growth and characterization of yttrium iron garnet films on Si substrates by chemical solution deposition (CSD) technique

Xin Guo, Ying Chen, Genshui Wang, Yuanyuan Zhang, Jun Ge, Xiaodong Tang, Freddy Ponchel, Denis Remiens, Xianlin Dong

Yttrium Iron Garnet (YIG) films were prepared on Si substrates by Chemical Solution Deposition (CSD) technique using acetic acid and deionized water as solvents. Well-crystallized and crack-free YIG films were obtained when annealed at 750°C and 850°C respectively, showing a low surface roughness...
