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…

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…

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.…

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling…

A 4-fJ/spike artificial neuron in 65 nm CMOS technology

Ilias Sourikopoulos, Sara Hedayat, Christophe Loyez, Francois Danneville, Virginie Hoel, Eric Mercier, A. Cappy

As Moore's law reaches its end, traditional computing technology based on the Von Neumann architecture is facing fundamental limits. Among them is poor energy efficiency. This situation motivates the investigation of different processing information paradigms, such as the use of spiking neural…

Energy Consumption Models For MISO-UWB and TR-MISO-UWB Systems

Adil El Abboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

this paper, an energy consumption model is developed and exploited to evaluate the electrical energy consumption of ultra-wideband impulse radio (UWB-IR) systems. We develop the energy consumption models and our comparative study, on the one hand, for a system based single-input singleoutput (SISO…
