PbS quantum dots and ZnO nanowires for 3rd generation solar cells

Basma El Zein, El Hadj Dogheche, Enrico Traversa

Semiconductor nanostructures with low dimensions such as quantum dots and nanowires are considered as important building blocks for the third generation solar cells, due to their useful optical and electrical properties. Quantum dots and nanowires hold promising potency to improve the performance…

Mueller matrix optical and magneto-optical characterization of Bi-substituted gadolinium iron garnet for application in magnetoplasmonic structures

L. Halagacka, K. Postava, Mathias Vanwolleghem, Francois Vaurette, Jamal Ben Youssef, B. Dagens, J. Pistora

A ferromagnetic garnet, used as a magneto-optical (MO) material in magneto-photonic and magneto-plasmonic structures, is characterized. We present a general procedure to determine optical and magneto-optical functions of the magneto-optic garnet by using Mueller matrix ellipsometry. In the first…

Demonstrating kHz frequency actuation for conducting polymer microactuators

Ali Maziz, Cedric Plesse, Caroline Soyer, Claude Chevrot, Dominique Teyssié, Eric Cattan, Frederic Vidal

This paper reports results on ionic EAP micromuscles converting electrical into micromechanical response in open-air. Translation of small ion motion into large deformation in bending microactuator and its amplifi cation by fundamental resonant frequency are used as tools to demonstrate that small…

Approach-to-equilibrium molecular dynamics for thermal conductivies and boundary conductances

Pier Luca Palla, Evelyne Lampin, Pierre-Arnaud Francioso, Fabrizio Cleri

Thermal transport is simulated at the atomic scale by approach-to-equilibrium molecular dynamics simulations (AEMD) [1]. In this method, a hot and a cold regions are delimited, before the approach-to-equilibrium is simulated by releasing the thermal constraint. The temperature difference between…

UWB cooperatif radar for localization and communication dedicated to guided transport

Tarik Tahri, Yassin El Hillali, Laila Sakkila, Atika Rivenq

Wireless technology for communication and localization in train applications are widely used. Ultra wide band appears as a very suitable technology for this kind of application, due to its large bandwidth, also to its good resistance to the interference and to multipath. In this paper, a new system…

Angle-dependent ray tracing simulations of reflections on pyramidal textures for silicon solar cells

Vincent Magnin, Joseph Harari, Mathieu Halbwax, S Bastide, D Cherfi, Jean-Pierre Vilcot

Pyramidal textures are commonly used to reduce reflections from silicon solar cells and improve light absorption by light trapping. They are generally modelled or characterized under normal incidence. In this work, a monolayer 3D ray tracing program taking into account the polarisation of light…

Modulation recognition for MIMO relaying broadcast channels with direct link

Wassim Ben Chikha, Iyad Dayoub, Walaa Hamouda, Rabah Attia

In this letter, we investigate the performance of modulation identification based on pattern recognition approach using the decision tree (J48) classifier, for multiple-inputmultipleoutput (MIMO) relaying broadcast channels with direct link (source-to-destination). The proposed system identifies…

Hybrid organic-inorganic nanocomposites for terahertz applications

D. Hourlier-Bahloul, Srisaran Venkatachalam, Christophe Boyaval, Guillaume Ducournau, Y. Blum, Jean-Francois Lampin

The TeraHertz (THz) portion corresponds to the part of the electromagnetic spectrum having frequencies ranging from 0.3 to 10 THz. Unlike UV or X-rays, THz photons are not energetic enough to break chemical bonds or to ionize atoms or molecules. These radiations have found widespread applications…

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances…
