Lead-free piezoelectric thin films by sol-gel method : synthesis and characterization

Sara Abou Dargham, Freddy Ponchel, A. Khoury, Jamal Assaad, Denis Remiens, D. Zaouk

The most common piezoelectric materials are lead zirconate titanate (Pb(Zr,Ti)O3 or PZT) due to their ferroelectric and piezoelectric properties. However, due to the effects of lead toxicity, it has recently desired to develop lead-free piezoelectric materials for environmental protection.…

Propagation of acoustic wave’s motion in orthotropic Cylinders of infinite length

Ismail Naciri, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, Tadeusz Gryba

We report, in the present work, a numerical method for investigating guided waves propagation in a homogeneous infinite cylinder composed of elastic material. This method makes use of Legendre polynomials series and harmonic function to express different displacement components which are introduced…

Synthesis of In0.1Ga0.9N/GaN structures grown by MOCVD and MBE for high speed optoelectronics

Bandar Alshehri, Karim Dogheche, Sofiane Belahsene, Bilal Janjua, Abderrahim Ramdane, Gilles Patriarche, Tien Khee Ng, Boon Seng Ooi, Didier Decoster, El Hadj Dogheche

In this work, we report a comparative investigation of InxGa1-xN (SL) and InxGa1-xN/GaN (MQW) structures with an indium content equivalent to x=10%. Both structures are grown on (0001) sapphire substrates using MOCVD and MBE growth techniques. Optical properties are evaluated for samples using PL…

First power performance demonstration of flexible AlGaN/GaN high electron mobility transistor

Sarra Mhedhbi, Marie Lesecq, Philippe Altuntas, N. Defrance, Etienne Okada, Yvon Cordier, Benjamin Damilano, Gema Tabares Jimenez, Abel Ebongue, Virginie Hoel

This letter reports on the first demonstration of microwave power performance at 10 GHz on flexible AlGaN/GaN high-electron-mobility transistor (HEMT). A maximum dc current density of 620 mA/mm at V-GS = 0 V and a peak extrinsic transconductance of 293 mS/mm are obtained for a 2 x 50 x 0.1 mu m(2)…

Surface acoustic wave characterization of optical sol-gel thin layers

Dame Fall, François Compoint, Marc Duquennoy, Hervé Piombini, Mohammadi Ouaftouh, Frédéric Jenot, Bogdan Piwakowski, Philippe Belleville, Chrystel Ambard

Controlling the thin film deposition and mechanical properties of materials is a major challenge in several fields of application. We are more particularly interested in the characterization of optical thin layers produced using sol-gel processes to reduce laser-induced damage. The mechanical…

On classifiers for blind feature‐based automatic modulation classification over multiple‐input–multiple‐output channels

Sofiane Kharbech, Iyad Dayoub, Marie Zwingelstein, Eric Pierre Simon

Modulation recognition is crucial for a good environmental awareness required by cognitive radio systems. In this study, the authors design and compare models of four among the most commonly used classifiers for feature-based automatic modulation classification (FB-AMC) algorithms. Classifiers…

Guided waves in general anisotropic layered rectangular rods: An extended orthogonal polynomial approach

J.G. Yu, Jean-Etienne Lefebvre, Ch. Zhang

The orthogonal polynomial approach has been used to solve the guided wave propagation in structures for about 20 years, but was limited until now to one-dimensional structures, that is, structures with a finite dimension in only one direction, such as horizontally infinite flat plates and axially…
