[Invited] MEMS-based atomic force microscopy probes: from electromechanical to optomechanical vibrating sensors

Bernard Legrand, Lucien Schwab, Pierre Allain, Ivan Favero, Marc Faucher, Didier Theron, Benjamin Walter, Jean-Paul Salvetat, Sébastien Hentz, Guillaume Jourdan

Scanning probe microscopy has been one of the most important instrumental discoveries during the last quarter of the last century. In particular, atomic force microscopy (AFM) is a cross-disciplinary technique able to provide sample morphology down to the atomic scale. It offers invaluable tools to…

Making Historical Musical Instruments Speak

Henri Boutin, Stéphane Vaiedelich, Arthur Paté, Givois Arthur, Benoît Fabre, Sandie Le Conte, Jean-Loïc Le Carrou

Musical instruments can be considered objects that have been empirically optimized for centuries. Depending on geography and epoch, these optimizations have followed or boosted the evolution of music itself, as instrument-making choices, playing techniques and sound aesthetics are greatly…

UWB radar recognition system based on HOS and SVMs

Rahmad Sadli, Charles Tatkeu, Khadija Hamidoun, Yassin El Hillali, Atika Rivenq

This study proposes an original ultra-wideband short-range radar (UWB-SRR) recognition system based on higher-order statistics (HOS) and support vector machines (SVMs). The main purpose of this work is to improve the road safety by implementing these techniques for detection and recognition of the…

Performance of the structure AlxGa1-xAs1-yNy/Ge for solar cell applications

Wafa Bellil, Abdelkader Aissat, Jean-Pierre Vilcot

The aim of this modeling and simulation is to study the influence of the incorporation of nitrogen (N) and aluminum (Al) on the optoelectronic properties of the structure AlxGa1-xAs1-yNy/Ge, and then choose the right combination (N, Al) which gives us a better conversational efficiency of the…

Chemical nature of the anion antisite in dilute phosphide GaAs1−xPx alloy grown at low temperature

T. Demonchaux, K. K. Sossoe, M. M. Dzagli, J. P. Nys, Maxime Berthe, David Troadec, A. Addad, M. Veillerot, G. Patriarche, H. J. Von Bardeleben, M. Schnedler, Christophe Coinon, Isabelle Lefebvre, M. A. Mohou, D. Stievenard, Jean-Francois Lampin, Ph. Ebert, X. Wallart, B. Grandidier

While nonstoichiometric binary III-V compounds are known to contain group-V antisites, the growth of ternary alloys consisting of two group-V elements might give additional degrees of freedom in the chemical nature of these antisites. Using cross-sectional scanning tunneling microscopy (STM), we…

On the occurrence of size effects in the calculation of thermal conductivity by first-principles molecular dynamics: The case of glassy GeTe4

Évelyne Martin, Pier Luca Palla, Fabrizio Cleri, Assil Bouzid, Guido Ori, Sébastien Le Roux, Mauro Boero, Carlo Massobrio

The thermal conductivity of a glass can be obtained by first-principles molecular dynamics provided we exploit a methodology that has been termed the approach-to-equilibrium molecular dynamics (AEMD) [1] [2, Chap. 8]. In the present work, we investigate the occurrence of size effects by comparing…

Enhanced antibacterial activity of carbon dots functionalized with ampicillin combined with visible light triggered photodynamic effects

Roxana Jijie, Alexandre Barras, Julie Bouckaert, Nicoleta Dumitrascu, Sabine Szunerits, Rabah Boukherroub

In the last years, carbon-based nanomaterials have attracted considerable attention in a wide range of fields, particularly in biomedicine, owing to their remarkable photo-physical and chemical properties. In this study, we demonstrate that amine-terminated carbon dots (CDs-NH2) functionalized with…

Automatic modulation classification for D-STBC cooperative relaying networks

Hakim Tayakout, Iyad Dayoub, Khalida Ghanem, Hicham Bousbia-Salah

Automatic modulation classification (AMC) has been used as a crucial component to improve the overall performance in cognitive radio system, thereby allowing any user to promote secure and reliable communication. In this letter, we propose a semi-blind AMC approach based on a simplified distributed…

Highly confined Love waves modes by defect states in a holey SiO2 /quartz phononic crystal

Yuxin Liu, Abdelkrim Talbi, Philippe Pernod, Olivier Bou Matar

Highly confined Love modes are demonstrated in a phononic crystal based on a square array of etched holes in SiO 2 deposited on the ST-cut quartz. An optimal choice of the geometrical parameters contributes to a wide stop-band for shear waves' modes. The introduction of a defect by removing…

Enhanced photovoltaic performance of inverted polymer solar cells through atomic layer deposited $Al_{2}$$O_{3}$ passivation of ZnO-nanoparticle buffer layer

Bin Wei, Zhenyu Tang, Shuanglong Wang, Cunping Qin, Chunya Li, D Ding, Yulai Gao, X. Portier, F. Gourbilleau, D. Stievenard, Tao Xu

In this work, an atomic layer deposited (ALD) $Al_{2}$$O_{3}$ ultrathin layer was introduced to passivate the ZnO-nanoparticle (NP) buffer layer of inverted polymer solar cells (PSCs) based on P3HT:PCBM. The surface morphology of the ZnO-NP/$Al_{2}$$O_{3}$ interface was systematically analyzed by…
