Competing Activities in Social Networks

Mohamed Moez Belhaj, Frédéric Deroïan

We consider a society in which each agent has one unit of a resource to allocate between two activities. Agents are organized in a social network, and each activity generates complementarities between neighbors. We find multiplicity of equilibrium for high intensity of interaction, and we…

Limitations of the impulse response of GaAs MSM photoswitch

Sabah Benzeghda, Farida Hobar, Didier Decoster, Jean-Francois Lampin

As symmetrical data characteristics I (V) of the Metal-Semiconductor-Metal (MSM) photodetector, we wondered how this device can be used as a photoswitch as well as the low temperature on GaAs photoconductive generally used for this purpose. The impulse response of interdigitated metal-semiconductor…

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…

Inkjet printed flexible transmission lines for high frequency applications up to 67 GHz

Mohamed Moez Belhaj, Wei Wei, Emiliano Pallecchi, Colin Mismer, Isabelle Roch-Jeune, Henri Happy

This letter introduces radio frequency(RF) characterization of ink-jet printed coplanar waveguides (CPW) with and without strain. Kapton is selected as flexible substrate with different sintering temperature. With optimized inkjet printing parameters, well defined patterns with high resolution…

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…

Optical properties of gallium nitride heterostructures grown on silicon for waveguiding application

Irma Saraswati, Arnaud Stolz, S. Ko, El Hadj Dogheche, Nji Raden Poespawati, Retno Wigajatri, Didier Decoster

Gallium nitride (GaN) on silicon (Si) is governed by the possibility to use this family of semiconductor for novel optoelectronic devices. GaN layers are deposited by MOCVD on silicon Si (111) using AlGaN buffer layer. We have studied the microstructure quality of the films. From SEM, TEM and AFM…

Phononic crystals patterning by e-beam lithography "dots on the fly" methodology for integration into thermoelectric energy converters

Valeria Lacatena, Maciej Haras, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki, Emmanuel Dubois

A phononic engineered pattern is conceptualized and realized to hinder the phonons propagation and reduce the lattice thermal conductivity. The pattern fabrication methodology is shown and the procedure of integration on suspended membrane for thermal conductivity characterization is depicted. The…
