Ambipolar spin diffusion in p-type GaAs: A case where spin diffuses more than charge

Fabian Cadiz, V. Notot, J. Filipovic, D. Paget, C. Weber, L. Martinelli, A. Rowe, S. Arscott

We investigate the diffusion of charge and spin at 15 K in p-type GaAs, combining transient-grating and energy-resolved microluminescence measurements to cover a broad range of photoelectron density. At very low optical power, in a unipolar nondegenerate regime, charge and spin diffuse at the same…

Passive UHF RFID system evaluation in a retail environment

Hadi Farhat, Plamen Iliev, Philippe Mariage, Nathalie Rolland

The work in this paper presents the study of the influence of a particular environment on the performances of passive UHF RFID tags attached to products presented in a retail store. The effects of the near-field environment and of the far field environment are successively and separately…

Thermal conductivity of glassy GeTe4 by first-principles molecular dynamics

Assil Bouzid, Hayat Zaoui, Pier Luca Palla, Guido Ori, Mauro Boero, Carlo Massobrio, Fabrizio Cleri, Évelyne Martin

A transient thermal regime is achieved in glassy GeTe4 by first-principles molecular dynamics following the recently proposed “approach-to-equilibrium” methodology. The temporal and spatial evolution of the temperature do comply with the time-dependent solution of the heat equation. We demonstrate…

Correction to: Effect of incubation duration, growth temperature, and abiotic surface type on cell surface properties, adhesion and pathogenicity of biofilm-detached Staphylococcus aureus cells

Oussama Khelissa, Charafeddine Jama, Marwan Abdallah, Rabah Boukherroub, Christine Faille, Nour-Eddine Chihib

Following publication of the original article (Khelissa et al. 2017), the authors reported that the legend for Fig. 3 contained an error. Instead of “Adhesion of planktonic and biofilm-detached Staphylococcus aureus cells on stainless steel and polycarbonate. Cell cultures were grown at 20, 30 and…

Low Source/Drain Contact Resistance for AlGaN/GaN HEMTs with High Al Concentration and Si-HP [111] Substrate

Steven Duffy, Brahim Benbakhti, Maghnia Mattalah, Wei Zhang, Meriem Bouchilaoun, Mohammed Boucherta, Karol Kalna, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

An optimized fabrication process of ohmic contacts is proposed to reduce the source/drain access resistance (RC) and enhance DC/RF performance of AlGaN/GaN HEMTs with a high Al concentration. We show that source/drain RC can be considerably lowered by (i) optimally etching into the barrier layer…

Design, fabrication and characterization of a new wideband antenna based on a Polyaniline/Carbon coated Cobalt composite

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, S. Bergheul, T. Lasri

The new generation of polymer materials has the facility to conduct electricity, radiate and concurrently be flexible. Accordingly, the possibility of implementation of a flexible antenna opens the door to many interesting applications including body-worn ones. This paper presents the design of a…

Study of the positioning of wireless sensors for communication at 2.4 GHz inside the train

Ulrich Biaou, Sara Iben Jellal, Michael Bocquet, S. Baranowski, Atika Rivenq, Philippe Mariage

The benefits of wireless sensor networks (WSN) offer many possibilities for the management of energy systems, which are actually based on wired systems. The need of new services on-board the train and of cables lengths reduction promote the use of wireless sensor networks in trains. Then,…

Acoustic source localization based on the similarity rate between frequency-time images

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

Many studies in different domains have shown the possibility of extracting information from a medium by exploiting the natural acoustic noise present in such medium. Recently, the promising potential of a passive acoustic technique, based on the correlation of the ambient noise for controlling the…
