Impact of Gate Drain Spacing on Low-Frequency Noise Performance of In Situ SiN Passivated InAlGaN/GaN MIS-HEMTs

Mehdi Rzin, Jean-Marc Routoure, Bruno Guillet, Laurence Méchin, Magali Morales, Cédric Lacam, Piero Gamarra, Pierre Ruterana, F Medjdoub

In this paper we investigated the gate–drain access region spacing (L GD) effect on electrical and noise performance of InAlGaN/GaN metal– insulator–semiconductor high electron mobility transistors (MIS-HEMTs) using in situ SiN cap layer as gate insulator. Different L GD of InAlGaN/GaN MIS-HEMTs...

Atomic-scale structure of the glassy Ge 2 Sb 2 Te 5 phase change material: A quantitative assessment via first-principles molecular dynamics

Assil Bouzid, Guido Ori, Mauro Boero, Evelyne Lampin, Carlo Massobrio

The amorphous structure of the phase change material Ge2Sb2Te5 (GST) has been the object of controversial structural models. By employing first-principles molecular dynamics within density functional theory, we are able to obtain quantitative agreement with experimental structural findings for the...

Wireless monitoring system for lightweight aircraft landing gear

Christophe Delebarre, Sébastien Grondel, Samuel Dupont, F Rouvarel, M Yoshida

Mass repartition onboard lightweight aircraft is a crucial problem as it may generate difficulties for the pilot during the landing phase. Being able for the pilot to land the plane properly is of course an important aspect for safety, but also for structure integrity. So the mass repartition...

High Frequency Acoustic On-Chip Integration for Particle Characterization and Manipulation in Microfluidics

Sizhe Li, Julien Carlier, Malika Toubal, Huiqin Liu, Pierre Campistron, Dorothee Callens, Georges Nassar, Bertrand Nongaillard, Shishang Guo

This letter presents a microfluidic device that integrates high frequency (650 MHz) bulk acoustic waves for the realization of particle handling on-chip. The core structure of the microfluidic chip is made up of a confocal lens, a vertical reflection wall, and a ZnO film transducer coupled with a...

Zero echo time MRI- only treatment planning for radiation therapy of brain tumors after resection

C. Boydev, B. Demol, David Pasquier, Hervé Saint-Jalmes, G. Delpon, N. Reynaert

Using magnetic resonance imaging (MRI) as the sole imaging modality for patient modeling in radiation therapy (RT) is a challenging task due to the need to derive electron density information from MRI and construct a so-called pseudo-computed tomography (pCT) image. We have previously published a...

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...

New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

Eloïse Vidal, Nicolas Sturmel, Christine Guillemot, Patrick Corlay, François-Xavier Coudoux

In this paper, we introduce two perceptual filters as pre-processing techniques to reduce the bitrate of compressed high-definition (HD) video sequences at constant visual quality. The goal of these perceptual filters is to remove spurious noise and insignificant details from the original video...

3D patterning of silicon by contact etching with anodically biased nanoporous gold electrodes

Encarnación Torralba, Mathieu Halbwax, Taha El Assimi, Marin Fouchier, Vincent Magnin, Joseph Harari, Jean-Pierre Vilcot, Sylvain Le Gall, Raphaël Lachaume, Christine Cachet-Vivier, Stéphane Bastide

A novel strategy to achieve 3D pattern transfer into silicon in a single step without using lithography is presented. Etching is performed electrochemically in HF media by contacting silicon with a positively biased, patterned, metal electrode. Dissolution is localized at the Si/metal contacts and...
