Transport properties of a thin GaN channel formed in an Al0.9Ga0.1N/GaN heterostructure grown on AlN/sapphire template

Julien Bassaler, Rémi Comyn, Catherine Bougerol, Yvon Cordier, Farid Medjdoub, Philippe Ferrandis

Despite a high lateral breakdown voltage above 10 kV for large contact distances and a breakdown field of 5 MV cm −1 for short contact distances, an Al 0.9 Ga 0.1 N/GaN heterostructure with an 8 nm strained GaN channel grown on an AlN/sapphire template suffers from a low and anisotropic mobility....

Exploiting Non-idealities of Resistive Switching Memories for Efficient Machine Learning

Victor Yon, Amirali Amirsoleimani, Fabien Alibart, Roger Melko, Dominique Drouin, Yann Beilliard

Novel computing architectures based on resistive switching memories (also known as memristors or RRAMs) have been shown to be promising approaches for tackling the energy inefficiency of deep learning and spiking neural networks. However, resistive switch technology is immature and suffers from...

Étude et réalisation de métamatériaux acoustiques architecturés, Studies and realization of architectured acoustical metamaterial

Arthur Terroir

Dans le cadre de l'acoustique sous-marine, la détection de bâtiments est aujourd'hui un sujet largement étudié. Les revêtements de coques permettent d'échapper à cette détection mais il est nécessaire d'améliorer leurs performances pour suivre le développement des systèmes SONAR..., In the framework of underwater acoustics, detection of submerged vehicles is widely studied. Hull coatings are used to avoid such detection. Due to the enhancement of SONAR system low frequency performance, hull coatings must be improved.Acoustic metamaterials can be useful for this purpose thanks...

Nanorobotics and automated platform for microwave characterization of liquids using coaxial evanescent probe, Plate-forme robotisée et automatisée pour la caractérisation microonde par sonde coaxiale évanescente en milieu liquide

Ronan Petit, Mohamed Sebbache, Kamel Haddadi

A measurement platform for microwave characterization of liquids is presented. Coaxial probes using evanescent near-fields are designed and realized to mitigate the lack of spatial resolution of conventional open-ended coaxial probes. The liquid under test is placed on a XYZ piezo-based positioning...
