Analyse de l'incertitude en métrologie on-wafer nanométrique jusqu'à 110 GHz basée sur une calibration TRL

Daouda Seck, Djamel Allal, Kamel Haddadi

<div><p>La caractérisation précise des dispositifs hyperfréquences par mesures on-wafer repose sur une évaluation rigoureuse de l'incertitude associée aux paramètres S, en particulier aux fréquences millimétriques. Cet article présente une approche métrologique dédiée à l'…

Ultra-Low-Power Neuromorphic Spike Detector for Large-Scale Neural Interfaces

Louis Regnacq, Hicham Lahrach, Anna Kobzar, Nicolas Lefoulon, Rédha Kassi, Pascal Mariot, A. Cappy, Christel Vanbesien, Alexis Vlandas, Christophe Loyez, Virginie Hoel

This work presents an ultra-low-power analog neuromorphic architecture for spike detection in large-scale neural interfaces. The goal is to reduce the amount of data transmitted by the implant by sending only detected spike timestamps. The proposed approach is inspired by sensory neurons connected…

Enhancing RF Power and Efficiency through Trapping Mitigation in Buffer-Free QuanFINE GaN HEMT

Anders Lundskog, Lyes Ben Hammou, François Grandpierron, Elodie Carneiro, Katir Ziouche, Etienne Okada, Jr-T. Chen, Farid Medjdoub

<div><p>We investigated AlGaN/GaN HEMTs fabricated on SweGaN's buffer-free QuanFINE GaN-on-SiC platform to mitigate trapping and enhance RF performance. Two epitaxial designs were compared: a baseline structure and one incorporating a 100 nm Al0.2Ga0.8N back barrier. Both share an…

Stabilization of the Li3PS4/Li interface by a 4 nm Al2O3 coating studied by in situ HAXPES

Lucía Pérez Ramírez, Jonas Sottmann, Benjamin Hennequart, Muath Radi, Maxime Hallot, Christophe Lethien, Lenart Dudy, Jean-Pascal Rueff, Rémi Dedryvère

Li-metal based All-Solid-State Batteries (ASSBs) offer a safer and higher-energy alternative to conventional lithium-ion batteries, but their performances are hindered by interfacial instability between the solid-state electrolyte (SSE) and lithium metal electrode. To stabilize the interface, a…

Realizing high performance flexible multilevel memory based on charge storage in Au nanoparticles and electrets

Shuo Li, Khaoula Ferchichi, Hui Zhang, You Yin, Kamal Lmimouni

In this paper, we report on the pentacene-based field-effect transistors (FETs) and flexible nano-floating gate-based transistor memory (NFGM) devices that were fabricated on ultra-flexible 2 μm Parylene C, deposited on different substrates. All thin-film layers can be deposited at low temperatures…

Investigation of thickness dependences of interfacial magnetic properties of ( Pt / Co / W ) 5 -based multilayers

R. Sbiaa, W. Fotso, M. Hafiz, M. Ramu, Nicolas Tiercelin, S. Chérif, A. Lisfi, Y. Roussigné, S. Piramanayagam, M. Belmeguenai

We investigated the thickness dependences of the interfacial Dzyaloshinskii-Moriya interaction (DMI) and the perpendicular magnetic anisotropy (PMA) in (Pt/Co/W)5 multilayers by systematically varying the Co (from 1.3 to 1.9 nm) and W (from 0 to 3 nm) layer thicknesses. Vibrating sample…
