We report the electron-transport properties of a new photoaddressable molecular switch. The switching process relies on a new concept based on linear π-conjugated dynamic systems, in which the geometry and, hence, the electronic properties of an oligothiophene chain can be reversibly modified by…

Influence of viscosity on acoustic streaming in sessile droplets: an experimental and a numerical study with a Streaming Source Spatial Filtering (SSSF) method

Antoine Riaud, Michael Baudoin, Olivier Bou Matar, Jean-Louis Thomas, Philippe Brunet

When an acoustic wave travels in a lossy medium such as a liquid, it progressively transfers its pseudo-momentum to the fluid, which results in a steady flow called acoustic streaming. This phenomenon involves a balance between sound attenuation and shear, such that the streaming flow does not…

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…

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…
