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.…

Tuning the Cation Ordering with the Deposition Pressure in Sputtered LiMn1.5Ni0.5O4 Thin Film Deposited on Functional Current Collectors for Li-Ion Microbattery Applications

Manon Létiche, Maxime Hallot, Marielle Huve, Thierry Brousse, Pascal Roussel, C. Lethien

The development of high voltage spinel LiMn1.5Ni0.5O4 (LMNO) sputtered thin films on functional current collector was reported within the framework of this study. We have first solved the technological issue due to the PtSi phase which originates from the interdiffusion between silicon wafer and…

Experimental investigation of the lateral resolution of a homemade near field microwave microscope

Tianjun Lin, S. Gu, T. Lasri

In this paper an experimental investigation of the lateral resolution of a homemade near field microwave microscope (NFMM) is reported. The optimal lateral resolution is studied by a thorough analysis of the influence of critical parameters such as the stand-off distance, the tip apex size and the…

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…

IoT predictive application for DC motor control using radio frequency links

R. Kouki, A. Boé, T. Vantroys, F. Bouani

The Internet of things (IoT) becomes a new solution for the future industry. It aims to provide an intelligent environment to control systems in real time. We propose an embedded predictive application in the Wireless Networked Control Systems (W-NCS) to control a DC motor via RF links, under the…
