ScAlN/GaN-on-Si (111) HEMTs for RF applications

Seif El Whibi, Nagesh Bhat, Yassine Fouzi, Nicolas Defrance, Jean-Claude de Jaeger, Zahia Bougrioua, Florian Bartoli, Maxime Hugues, Yvon Cordier, Marie Lesecq

ScAlN is a promising barrier material for next generation RF high electron mobility transistors, outperforming AlGaN thanks a higher 2-dimensional electron gas (2DEG) density and a thinner barrier with a lower lattice mismatch with GaN. A sub-10 nm barrier ScAlN/GaN heterostructure, grown by...

Drying Behavior of Flax Stems at Different Degrees of Dew Retting Under Simulated Rainfall: Implications for Smart Agriculture and Sensor Development

Ali Reda, Lionel Buchaillot, Steve Arscott

Dew retting of flax stems is a key agricultural process which facilitates fiber extraction from parent stems. If sensors are to be developed to monitor the degree of retting for optimal fiber extraction, then stem characteristics such as water uptake and loss need to be accurately known. Here, the...

Effect of High Temperature RF Stress on the Trapping Behavior of Carbon Doped AlN/GaN/AlGaN HEMTs

Lyes Ben-Hammou, François Grandpierron, Elodie Carneiro, Katir Harrouche, Etienne Okada, Gilles Patriarche, Farid Medjdoub

This study investigates the impact of short-term hightemperature operating life (HTOL) reliability testing on the trapping behavior and power performance of carbon-doped AlN/GaN/AlGaN High Electron Mobility Transistors (HEMTs). HTOL stress can lead to significant degradation in key performance...

Experimental Demonstration of 73 Gb/s QPSK and 150 Gb/s QAM-32 Wireless Data Links in the Sub-THz Band Through Frequency Selective Surface Filters

Walter Fuscaldo, Daniele Pirrone, Dimitrios C Zografopoulos, Antonio Ferraro, Pascal Szriftgiser, Guillaume Ducournau, Romeo Beccherelli

Investigations on the beneficial effects of microfabricated frequency selective surfaces (FSS) filters in terahertz (THz) wireless links have been recently proposed for amplitude-only on-off keying modulation schemes. Preliminary results on the error performance of amplitude-phase modulations were...

Leveraging 3GPP Features and Optimization Techniques for 5G NR-V2X Resource Allocation: A Survey

Chaeriah Bin Ali Wael, El Hadj Dogheche, Nasrullah Armi, Agus Subekti, Iyad Dayoub

Cellular Vehicle-to-everything (C-V2X) communication is critical for Intelligent Transportation Systems (ITS), facilitating information exchange among road users and infrastructure. Since its first introduction in rel-15 by 3GPP, 5G NR-V2X features have continued to evolve, aiming to support...

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...

Brain‐Inspired Polymer Dendrite Networks for Morphology‐Dependent Computing Hardware

Corentin Scholaert, Yannick Coffinier, Sébastien Pecqueur, Fabien Alibart

Process variation is always a challenge to mitigate in electronics. This especially holds true for organic semiconductors, where reproducibility concerns hinder industrialization. Challenging this concept, it shows AC-electropolymerization to be a powerful platform for the development of morphology...
