Combined nanomechanical and nanomagnetic analysis of magnetoelectric memories

S. Giordano, Yannick Dusch, Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky

Magneto-electro-elastic and multiferroic materials can be combined in appealing nanostructures characterized by the coexistence and coupling of electric, magnetic, and mechanical phases with potential applications in novel multifunctional devices. Here, we derive a theory for nonvolatile room-…

Control of gallium incorporation in sol–gel derived CuIn(1−x)GaxS2 thin films for photovoltaic applications

Yoan Bourlier, Odile Cristini Robbe, Christophe Lethien, Pascal Roussel, Aymeric Pastre, Malek Zegaoui, Nathalie Rolland, Mohamed Bouazaoui, Rémy Bernard

In this paper, we report the elaboration of Cu(In,Ga)S2 chalcopyrite thin films via a sol–gel process. To reach this aim, solutions containing copper, indium and gallium complexes were prepared. These solutions were thereafter spin-coated onto the soda lime glass substrates and calcined, leading to…

High speed electromechanical response of ionic microactuators

Ali Maziz, Cedric Plesse, Caroline Soyer, Eric Cattan, Frédéric Vidal

This paper presents the synthesis and characterization of thin and ultra-fast conducting polymer microactuators which can operate in the open air. Compared to all previous existing electronic conducting polymer based microactuators, this approach deals with the synthesis of robust interpenetrating…

Experimental investigation of electromagnetic reverberation characteristics as a function of UWB frequencies

Aliou Bamba, Maria-Teresa Martinez-Ingles, Davy Gaillot, Emmeric Tanghe, Brecht Hanssens, Jose-Maria Molina-Garcia-Pardo, M. Lienard, Luc Martens, Wout Joseph

The electromagnetic reverberation time characteristics of indoor environments are experimentally investigated from 2 to 10 GHz. At a given frequency, the reverberation time is observed to be approximately constant for bandwidths up to 900 MHz (or larger). Moreover, the reverberation time decreases…

PZT Nanofilm-Based Wafer Scale Nanoresonators

Denis Dezest, Fabrice Mathieu, Laurent Mazenq, Liviu Nicu, Caroline Soyer, Jean Costecalde, Olivier Thomas, Denis Remiens

In this work, we present an unprecedented level of integration of piezoelectric actuation means on arrays of functional nanoresonators at the wafer scale. We use 150-nm thin lead titanate zirconate (PZT) as piezoelectric material mainly because of its excellent actuation properties even when…

Application de la radio intelligente dans le contexte ferroviaire, Application of Cognitive Radio in the Context of Railways

Sofiane Kharbech

Un système de transport ferroviaire intelligent est essentiellement caractérisé par son niveau d'autonomie de prise de décision en fonction des conditions qui lui sont extérieurs. Afin de renforcer son intelligence et son autonomie, cette nouvelle génération de systèmes de transport intègre…, Any intelligent railway transport system is mainly characterized by its autonomy in making decisions in terms of its external conditions. In order to improve its cognition and autonomy, this new generation of transport systems integrates multiple technologies and standards of communication and…
