Dynamic switching of ferrocene and plasmonic interactions in Au/self-assembled monolayer/single Ag nanocube molecular junctions

Mariem Ben Youssef, Peeranuch Poungsripong, Hugo Bidotti, Halidou Abdoul-Yasset, Didier Gigmes, Olivier Margeat, Beniamino Sciacca, Judikaël Le Rouzo, David Duché, Dominique Vuillaume

We report the redox switching of ferrocene moieties embedded in a double tunnel barrier plasmonic cavity fabricated from a click-chemistry self-assembled monolayers of ferrocenyl-alkylthiol on ultra flat gold surfaces, connected to a single poly(vinylpyrrolidone) capped silver nanocube, AgNC, which…

Surface oxidation and oxygen incorporation in ScAlN films grown by molecular beam epitaxy

Valentina Gallardo-Mödinger, Frédéric Georgi, Xavier Wallart, Ileana Florea, Philippe Vennéguès, Yvon Cordier, Maxime Hugues

Recently, there has been much interest in the ScAlN alloy, thanks to its various potential applications in high-frequency high-power, acoustoelectric, and ferroelectric devices. Nonetheless, these applications could be impaired by the presence of oxygen in the alloy and the formation of a surface…

Spintronic Terahertz Emitters with Integrated Metallic Terahertz Cavities

Adrien Wright, Martin Mičica, Pierre Koleják, Geoffrey Lezier, Kamil Postava, Jacques Hawecker, Anna de Vetter, Jérôme Tignon, Juliette Mangeney, Henri Jaffres, Romain Lebrun, Nicolas Tiercelin, M. Vanwolleghem, Sukhdeep Dhillon

Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses [1-2] . However, the efficiency of the optical-to-THz conversion remains limited.

Boosting hyperspectral image classification with Gate-Shift-Fuse mechanisms in a novel CNN-Transformer approach

Mohamed Fadhlallah Guerri, Cosimo Distante, Paolo Spagnolo, Abdelmalik Taleb-Ahmed

Hyperspectral Image (HSI) classification categorizes every pixel sample into distinct land-cover types. While CNN-based methods have demonstrated significant advances in feature representation, they often struggle with extracting deep features. On the other hand, transformer models excel in…

PE-CLIP: A Parameter-Efficient Fine-Tuning of Vision Language Models for Dynamic Facial Expression Recognition

Ibtissam Saadi, Abdenour Hadid, Douglas Cunningham, Abdelmalik Taleb-Ahmed, Yassin El Hillali

Vision-Language Models (VLMs) like CLIP offer promising solutions for Dynamic Facial Expression Recognition (DFER) but face challenges such as inefficient full fine-tuning, high complexity, and poor alignment between textual and visual representations. Additionally, existing methods struggle with…

Inverted BER Trends for Energy-Detected GRSM-MQAM Massive MIMO Downlink

Oshin Daoud, Haïfa Farès, Yahia Medjahdi, Laurent Clavier, Amor Nafkha

This work investigates Generalized Receiver Spatial Modulation (GRSM) in a massive MIMO downlink scenario over millimetre wave channels. While GRSM enhances spectral efficiency (SE) and reduces power consumption, indexing additional bits using the spatial dimension increases the vulnerability to…

Imagerie passive de couches sur substrats par corrélation de champ acoustique haute fréquence

Nada Ben Jafela, Lynda Chehami, Marc Duquennoy, Emmanuel Moulin, Nikolay Smagin, Dame Fall, Zakariae Oumekloul

Les structures couche sur substrat sont généralement sujettes à divers types de défauts, en particulier ceux liés au processus de fabrication lors de la croissance des films minces. Actuellement, une possibilité pour inspecter ces structures consiste à utiliser des transducteurs IDTs en émission et…

A Sub-400-nW Real-Time Event-Driven Spectrogram Extraction Unit in 28-nm FD-SOI CMOS for Keyword Spotting Application

Soufiane Mourrane, Benoit Larras, Sylvain Clerc, Andreia Cathelin, Antoine Frappé

Considering the power-hungry nature of speech processing, a keyword spotting (KWS) unit, used to detect multiple spoken words, is often integrated as a front-end layer. KWS systems are always active, and thus, it is extremely important to optimize the devoted power budget. In this context, this…
