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…

5G Waveforms for Railway

Michel Saideh, Marion Berbineau, Iyad Dayoub

In this paper we review the most promising 5G waveform candidates and their robustness to the Railway context and particularly the high speed. We surf in addition the compatibility of these waveforms to the short packet communication and the MIMO technologies which are fundamental components of…

Photothermally triggered on-demand insulin release from reduced graphene oxide modified hydrogels

Florina Teodorescu, Yavuz Oz, Gurvan Queniat, Amar Abderrahmani, Catherine Foulon, Marie Lecoeur, Rana Sanal, Amitav Sanyal, Rabah Boukherroub, Sabine Szunerits

On-demand delivery of therapeutics plays an essential role in simplifying and improving patient care. The high loading capacity of reduced graphene oxide (rGO) for drugs has made this matrix of particular interest for its hybridization with therapeutics. In this work, we describe the formulation of…

Topological protection of electronic states against disorder probed by their magnetic moment

Athmane Tadjine, Christophe Delerue

Magnetic moments (MMs) of electrons in topological insulator quantum dots (TI-QDs) are investigated using a model system, namely a multiorbital honeycomb lattice. Their nature and orientation with respect to the spin are studied. We show that large MMs are not specific to edge states in nontrivial…

A 65-nm CMOS 7fJ per synaptic event clique-based neural network in scalable architecture

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks are less complex than commonly used neural network models. They have a limited connectivity and are composed of simple functions. They are thus adapted to implement neuro-inspired computation units operating under severe energy constraints. This paper shows an ST 65-nm…
