Nonlinear modeling of AlN/GaN HEMT accounting for self-biasing effect during RF step stress: analysis and hard-SOA

Nasri Said, Damien Saugnon, K. Harrouche, F Medjdoub, N. Labat, N. Malbert, Jean-Guy Tartarin

In this study, we investigate the non-linear (NL) behavior of AlN/GaN HEMT technologies under gain compression when submitted to 10 GHz single-tone RF-step stress, which is crucial for millimetre-wave power application robustness. We evaluate AlN/GaN transistors, targeting high-power amplifiers…

Physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers for power electronics applications

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Adrien Bidaud, Pierre Brosselard, Eric Frayssinet, Florian Bartoli, Yvon Cordier, Farid Medjdoub, Dominique Planson, Cyril Buttay

This work presents physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers and associated quasi-vertical Schottky Barrier Diodes (SBDs). Samples GaN drift layers have globally a similar quality as examined by XRD, AFM Raman spectroscopy, C-V measurements and I-V…

Infrastructure intelligente pour l'allocation de puissance dans les systèmes MIMO de type cell-free

Philippe Mathieu, Antoine Nongaillard, Eric Pierre Simon

Les réseaux de télécommunication actuels, basés sur des stations centralisées, ne répondent pas aux besoins croissants en bande passante et aux nouveaux usages comme l'IoT ou les véhicules connectés. Le paradigme "cell-free" émerge comme une solution, distribuant des points d'…, Current telecommunication networks, based on centralized base stations, do not meet the growing demand for bandwidth and new uses such as IoT or connected vehicles. The "cell-free" paradigm emerges as a solution, distributing less powerful but more numerous access points over a wide area…

Thermoelastic properties of polycrystalline strontium titanium silicate Sr₂TiSi₂O₈ synthesized via the reactive sintering method

Oussama Zwein, Maurice Gonon, Sandra Abdelouhab, Isabella Mastroianni, Marc Duquennoy

The aim of the work presented in this paper is to investigate the thermoelastic properties of polycrystalline Sr-fresnoite Sr2TiSi2O8 (STS). On that purpose, Sr2TiSi2O8 samples were synthesized by solid state reactive sintering from SrCO3, TiO2 and SiO2 powders. The thermal expansion behaviour of…

In Vitro Evaluation of Antibacterial Properties of NIR-Light Responsive Alginate Hydrogels Embedding Polydopamine Nanoparticles

Sarah Defrançois, Alexandre Barras, Mickaël Maton, Patrice Woisel, Feng Hildebrand, Nicolas Blanchemain, Rabah Boukherroub, Joël Lyskawa

acterial infections are one of the most serious health problems worldwide and represent a significant threat to humans. In this article, we designed an injectable alginate-based hydrogel embedding polydopamine nanoparticles (nPDA) and applied it as a (nano)phototherapeutic agent and nanocarrier for…

Theoretical Framework for Semitransparent Organic Photovoltaics: Bridging Material Design with Optical Engineering

Baozhong Deng, Zhouyi Lu, Kaiwen Zheng, Bin Wei, Gaëtan Lévêque, Bruno Grandidier, Jianhua Zhang, Tao Xu

Semitransparent organic photovoltaics (ST‐OPVs) hold great promise for building‐integrated applications but encounter a critical trade‐off between power conversion efficiency (PCE) and visible transparency. This work addresses this challenge by introducing a novel theoretical framework that…

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Maya Marinova, Adrien Neri, Adrien Teurtrie, Francisco de la Peña, Damien Jacob, Alexandre Fadel, David Troadec

The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated…

Topology optimization of phoxonic crystals for maximizing dual bandgaps using GA-SIMP method

Bin Li, S S Nanthakumar, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

Phoxonic crystals are photonic-phononic or optomechanical periodic structures that simultaneously exhibit dual bandgaps. This allows for the confinement of both optical and elastic waves in cavities and waveguides, providing a powerful platform for novel optomechanical devices and systems. The…
