Low Source/Drain Contact Resistance for AlGaN/GaN HEMTs with High Al Concentration and Si-HP [111] Substrate

Steven Duffy, Brahim Benbakhti, Maghnia Mattalah, Wei Zhang, Meriem Bouchilaoun, Mohammed Boucherta, Karol Kalna, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

An optimized fabrication process of ohmic contacts is proposed to reduce the source/drain access resistance (RC) and enhance DC/RF performance of AlGaN/GaN HEMTs with a high Al concentration. We show that source/drain RC can be considerably lowered by (i) optimally etching into the barrier layer…

IEEE 802.11n Communications in the Presence of Frequency-Sweeping Interference Signals

Virginie Deniau, Christophe Gransart, Grecia Romero, Eric Pierre Simon, Joumana Farah

This paper presents an analysis of the impact of intentional electromagnetic (EM) interferences on the performance of Wi-Fi communications. The goal is to analyze the susceptibility of orthogonal frequency-division multiplexing (OFDM) signals and to understand how certain parameters of the…, Cet article présente une analyse de l'impact des interférences électromagnétiques intentionnelles (IEMI) sur la performance des communications Wi-Fi. L'objectif est d'analyser la susceptibilité des signaux de OFDM (Orthogonal Frequency Division Multiplex ) et de comprendre comment…

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…

Innovative Aeronautical Structural Health Monitoring Ultrasonic Sensor: From Autonomy to High Sensibility

Christophe Delebarre

Since aeronautical structures tend to be more and more sophisticated today, it becomes necessary to develop Non Destructive Testing techniques for the monitoring of last generation aircraft. This concept also called Structural Health Monitoring has as main objective to detect and locate damages…

Iron minerals within specific microfossil morphospecies of the 1.88 Ga Gunflint Formation

Kevin Lepot, Ahmed Addad, Andrew H. Knoll, Jian Wang, David Troadec, Armand Béché, Emmanuelle J. Javaux

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities…

Pillar-type acoustic metasurface

Yabin Jin, Bernard Bonello, Rayisa P. Moiseyenko, Yan Pennec, Olga Boyko, Bahram Djafari-Rouhani

We theoretically investigate acoustic metasurfaces consisting of either a single pillar or a line of identical pillars on a thin plate, and we report on the dependence on the geometrical parameters of both the monopolar compressional and dipolar bending modes. We show that for specific dimensions…
