Luminescence imaging of photoelectron spin precession during drift in a p-type GaAs microfabricated Hall bar

V. Notot, D. Paget, A. Rowe, L. Martinelli, Fabian Cadiz, S. Arscott

Using a microfabricated p-type GaAs Hall bar, it is shown that the combined application of co-planar electric and magnetic fields enables the observation of spatial oscillations of the photoluminescence circular polarization due to the precession of drifting spin-polarized photoelectrons.…

Energy Efficient Hardware and Improved Cluster-Tree Topology for Lifetime Prolongation in ZigBee Sensor Networks

Mourad Ouadou, Ouadoudi Zytoune, Yassin El Hillali, Atika Rivenq, Driss Aboutajdine

In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries. Many factors are involved in the energy consumption, and this issue may be considered as a cross-layer problem, from the…

Simulation Study of the Localization of a Near-Surface Crack Using an Air-Coupled Ultrasonic Sensor Array

Steven Delrue, Vladislav Aleshin, Mikael Sørensen, Lieven Lathauwer

The importance of Non-Destructive Testing (NDT) to check the integrity of materials in different fields of industry has increased significantly in recent years. Actually, industry demands NDT methods that allow fast (preferably non-contact) detection and localization of early-stage defects with…

Theoretical and experimental study of a thermal damper based on a CNT/PCM composite structure for transient electronic cooling

Christophe Kinkelin, Stéphane Lips, Ulrich Soupremanien, Vincent Remondière, Jean Dijon, Hélène Le Poche, Emmanuel Ollier, Malek Zegaoui, Nathalie Rolland, Paul-Alain Rolland, Sandrine Lhostis, Brigitte Descouts, Yann Kaplan, Frédéric Lefèvre

The present study focuses on a thermal damper that aims at smoothing the temperature peaks experienced by electronic components during transient solicitations. It consists of a silicon casing containing a densified or undensified carbon nanotube (CNT) array - linking directly both sides of the…

Generation of mW level in the 300-GHz band using resonant-cavity-enhanced unitraveling carrier photodiodes

Philipp Latzel, Fabio Pavanello, Maximilien Billet, Sara Bretin, Alexandre Beck, Mathias Vanwolleghem, Christophe Coinon, Xavier Wallart, Emilien Peytavit, Guillaume Ducournau, Mohammed Zaknoune, Jean-Francois Lampin

We present a resonant-cavity-enhanced broadband unitraveling carrier photodiode optimized for terahertz (THz) generation. It uses a novel semitransparent top-contact utilizing subwavelength apertures for enhanced optical transmission. The contact allows front-side illumination of the photodiode…

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…
