MEMS calorimetric transducers for flow separation detection and control

Cécile Ghouila-Houri, Abdelkrim Talbi, Romain Viard, Quentin Gallas, Eric Garnier, Alain Merlen, Philippe Pernod

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were developed for flow separation control. Based on thermal principle, the transducers measure the mean and fluctuating bidirectional shear stress that is particularly useful for flow separation detection. More than a...

High performance silicon nanowires/ruthenium nanoparticles micro-supercapacitors

Yasmina Bencheikh, Maxime Harnois, Roxana Jijie, Ahmed Addad, Pascal Roussel, Sabine Szunerits, Toufik Hadjersi, Seddik El Hak Abaidia, Rabah Boukherroub

The continuous increase of small electronic devices calls for small energy storage components, commonly known as micro-supercapacitors, that can ensure autonomous operation of these devices. In this work, we propose a simple and straightforward method to achieve high energy and power densities of a...

Magneto-Optical Study of the Anisotropic Piezoelectric Effect in a Ferroelectric Crystal

A. Klimov, Nicolas Tiercelin, Vladimir Preobrazhensky, A. Sigov, Philippe Pernod

The possibility of using the magneto-optical Kerr effect in thin magnetostrictive films to study the piezoelectric characteristics of ferroelectrics is demonstrated experimentally and theoretically. A 011 PMN-PT ferroelectric crystal with an N*(TbCo 2 /FeCo) magnetostrictive nanostructure deposited...

New millimeter wave generation scheme for MIMO-OFDM based Radio-over-Fiber system

M. El Yahyaoui, A. El Moussati, Ghaïs El Zein, Kamel Haddadi

This paper proposes a new scheme for the generation and transmission of a MIMO-OFDM signal over optical fiber using a single local oscillator (LO) at 15 GHz. This technique is based on subcarrier multiplexing and Optical Carrier Suppression (OCS) modulation using both Dual-Parallel Mach–Zehnder...

Cl₂/Ar based atomic layer etching of AlGaN layers

Sébastien Aroulanda, Olivier Patard, Philippe Altuntas, Nicolas Michel, Jorge Pereira, Cédric Lacam, Piero Gamarra, Sylvain L. Delage, N. Defrance, Jean-Claude de Jaeger, Christophe Gaquière

This paper reports on atomic layer etching of several III-N materials such as GaN, AlN, AlGaN, and InAlGaN based on a sequential surface modification by chlorine adsorption followed by a low energy Ar plasma exposure to remove the modified layer using a reactive ion etching system. A study on the...

Micro-Electro-Mechanical-Systems advances for measurements at small scales: the vertical silicon probes technology extended to nearfield optics

B. Walter, E. Mairiaux, Sophie Eliet, Jean-Francois Lampin, Marc Faucher

Instrumentation intending to go beyond the limits of current Atomic Force Microscope setups (AFM), and applications requiring AFM to be integrated in non-standards environmental conditions need sensors that overcome limitations given by available probes. We show that the vertical probe technology...
