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…

RAVID: Retrieval-Augmented Visual Detection: A Knowledge-Driven Approach for AI-Generated Image Identification

Mamadou Keita, Wassim Hamidouche, Hessen Bougueffa Eutamene, Abdelmalik Taleb-Ahmed, Abdenour Hadid

In this paper, we introduce RAVID, the first framework for AI-generated image detection that leverages visual retrieval-augmented generation (RAG). While RAG methods have shown promise in mitigating factual inaccuracies in foundation models, they have primarily focused on text, leaving visual…
