Electrical method for crosstalk cancellation in transducer arrays

Abdelmajid Bybi, Christian Granger, Sébastien Grondel, Anne-Christine Hladky, Jamal Assaad

In this paper, we report a new and simple electrical method to cancel crosstalk in the acoustical arrays. This solution has several advantages compared with that proposed in a previous paper (Bybi et al 2013) [17] where adapted electrical voltages were applied to each neighboring element of the…

On the correlation between kink effect and effective mobility in InAlN/GaN HEMTs

Philippe Altuntas, N. Defrance, Marie Lesecq, Alain Agboton, Rezki Ouhachi, Etienne Okada, Christophe Gaquière, Jean-Claude de Jaeger, Éric Frayssinet, Yvon Cordier

This paper reports on the kink effect observed in InAlN/GaN high electron mobility transistors. Electrical characterizations were carried out to point out the influence of this phenomenon on transistor behaviour. It is demonstrated that the kink effect is directly correlated to shallow traps…

Thermoelectric infrared microsensors based on a periodically suspended thermopile integrating nanostructured Ge/SiGe quantum dots superlattice

Katir Ziouche, G. Savelli, Zahia Bougrioua, D. Hauser, P. Lejeune, P.M. Michon, Tuami Lasri, Didier Leclercq

This paper presents an original integration of polycrystalline SiGe-based quantum dots superlattices (QDSL) into Thermoelectric (TE) planar infrared microsensors (μSIR) fabricated using a CMOS technology. The nanostructuration in QDSL results into a considerably reduced thermal conductivity by a…

Miniaturized Microcantilever-based RF Microwave Probes Using MEMS Technologies

Jaouad Marzouk, S. Arscott, Kamel Haddadi, Tuami Lasri, Christophe Boyaval, Sylvie Lepilliet, Gilles Dambrine

In this study, miniaturized microwave cantilever-based probes - using silicon-on-insulator (SOI) technology - are proposed for the on-chip electrical characterization of nanodevices. In contrast with conventional on-wafer probing structures, small pad dimensions around 1 μm2 associated with a 4.5…

Synthesis and characterization of BNT thin films

Sara Abou Dargham, Jihane Jabbour, Youssef Zaatar, Jamal Assaad, Antonio Khoury, Denis Remiens, Doumit Zaouk

Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well…

Polymer based flapping-wing robotic insect : progress in design, fabrication and characterization

Alexandre Bontemps, Thomas Vanneste, Caroline Soyer, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

In the last decade, many researchers pursued the development of tiny flying robots inspired by natural flyers destined for the exploration of confined spaces, for example. Within this context, our main objective is to devise a flying robot bioinspired from insect in terms of size and wing…

Electrical characterization of semiconductor nanowires by scanning tunneling microscopy

Corentin Durand, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Renaud Leturcq, Philippe Caroff, B. Grandidier

In order to understand the structural and electronic properties of semiconductor nanowires, scanning tunneling microscopy is an appealing technique that can supplement transmission electron microscopies and conventional electrical characterization techniques. It is able to probe the surface of…

Electrical and chemical studies on Al2O3 passivation activation process

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Passivation process is a key feature to improve the efficiency of silicon solar cells. So far, a 20nm-thick layer of Al2O3 grown by Plasma Enhanced Atomic Layer Deposition (PE-ALD) followed by a 450°C anneal during 15 to 30 min gives the best results in surface carrier recombination velocities on p…
