Optimization and Comparison between the efficiency of GaNAsSb and GaInNAs single solar cells deposed on GaAs

Wafa Bellil, Abdelkader Aissat, Jean-Pierre Vilcot

In this work we study and optimize the single solar cell efficiency of GaNxAs1-x-ySby and Ga1-xInxNyAs1-y deposed on GaAs. The solar cells are simulated, in the aim to find the best concentration of nitrogen and antimony for GaNxAs1-x-ySby, and indium and nitrogen for Ga1-xInxNyAs1-y which gives us…

Impact of the in situ SiN Thickness on Low-Frequency Noise in MOVPE InAlGaN/GaN HEMTs

M. Rzin, B. Guillet, Laurence Méchin, P. Gamarra, C. Lacam, F Medjdoub, J.-M. Routoure

This article reports on sub-10-nm quater-nary barrier InAlGaN/GaN high electron mobility transistors (HEMTs) grown by metal-organic-vapor-phase-epitaxy (MOVPE) with an in situ SiN passivation layer and an ultra-short gate length of 200 nm. Two batches of HEMTs with two SiN thicknesses (t SiN) of 14…

Six-port technology for millimeter-wave metrology

Kamel Haddadi, Christophe Loyez, Katir Ziouche

The six-port measurement technique has played a major role in vector network analysis metrology, particularly within the community of national standards laboratories. Thanks to reduced hardware resource in contrast with conventional and well-established down-mixing heterodyne technique, this paper…

Energy-efficient techniques for combating the influence of reactive jamming using Non-Orthogonal Multiple Access and Distributed Antenna Systems

Joumana Farah, Jacques Akiki, Eric Pierre Simon

The aim of this work is to propose new approaches for maximizing the energy efficiency of downlink 5G mobile communication systems, in the presence of a reactive jammer. The concepts of non-orthogonal multiple access (NOMA) and distributed antenna systems (DAS) are exploited to devise joint subband…

On the impact of the covariance matrix size for spectrum sensing methods:beamforming versus eigenvalues

Kais Bouallegue, Matthieu Crussière, Iyad Dayoub

In this paper, we investigate the impact of the covariance matrix (CM) size of the received signal on the performance of spectrum sensing methods. Our analysis is based on two well-known methods of spectrum sensing (SS), one based on the eigenvalues called maximum-to minimum eigenvalue (MME) and…

Performance assessment of a small-size ocean wave energy harvester

Yongjie Sang, Bertrand Dubus

A lightweight electromechanical device is studied to harvest energy of ocean waves and supply electrical power to small-size ocean observation equipment such as sonobuoys. It is composed of a magnet fixed to the floating housing which follows the motion of the ocean surface and a moving coil…

Mesure indirecte des performances de LLR approché

Yasser Mestrah, Anne Savard, Alban Goupil, Guillaume Gelle, Laurent Clavier

Les réseaux sans fils sont de plus en plus denses et hétérogènes, entraînant l’accroissement très significatif de l’impact des interférences. De nombreux travaux ont montré la nature impulsive de cette interférence et la nécessité de modifier le calcul de la vraisemblance nécessaire au décodage.…
