Unsupervised and efficient learning in sparsely activated convolutional spiking neural networks enabled by voltage-dependent synaptic plasticity

Gaspard Goupy, Alexandre Juneau-Fecteau, Nikhil Garg, Ismael Balafrej, F. Alibart, Luc Frechette, Dominique Drouin, Yann Beilliard

Spiking neural networks (SNNs) are gaining attention due to their energy-efficient computing ability, making them relevant for implementation on low-power neuromorphic hardware. Their biological plausibility has permitted them to benefit from unsupervised learning with bio-inspired plasticity rules…

Securing Cyber-Physical Industrial Systems Against False Data Injection Attacks: A Hybrid Detection Approach

Khalil Guibene, Nadhir Messai, Marwane Ayaida

Cyber-physical industrial systems are internet-enabled physical entities embedded with computers and control components consisting of sensors and actuators. However, interconnecting the cyber and physical spaces led to new security challenges. This paper aims to come up with a novel approach to…

Martens hardness of Constantan thin films on (100) Si wafer: Improvement in contact area function in nanoindentation

Ayyoub Dziri, Alex Montagne, Francine Roudet, Katir Ziouche, Didier Chicot

This work presents a mechanical study by nanoindentation of Constantan thin films deposited by cathodic sputtering technique with an intermediate thin adhesion layer of titanium on a (100) silicon wafer substrate. A methodology based on a modified contact area function is proposed for a suitable…

Spin Seebeck effect and thermal properties of zigzag graphene nanoribbons with edge magnetism

Jing Li, Yann-Michel Niquet, Christophe Delerue

Zigzag graphene nanoribbons (GNRs), demonstrating edge magnetism, are fascinating materials for electronic and spintronic applications. In this paper, we investigate with explicit consideration of electron-phonon scattering the Seebeck effect and thermal conductivity at various carrier densities in…

Space-time Modulation in a Piezoelectric Phononic Crystal: Experimental Study in Sub-sonic and Sonic Regimes

Sarah Tessier Brothelande, Charles Croenne, Florian Allein, Jerome Vasseur, Bertrand Dubus

We experimentally study acoustic wave propagation in a spatio-temporally modulated system for different modulation speeds, up to the sonic regime when the modulation speed is similar to the wave propagation speed. The system under study is a piezoelectric phononic crystal whose electrical boundary…

Quasi van der Waals Epitaxy of Rhombohedral-Stacked Bilayer WSe₂ on GaP(111) Heterostructure

Aymen Mahmoudi, Meryem Bouaziz, Niels Chapuis, Geoffroy Kremer, Julien Chaste, Davide Romanin, Marco Pala, François Bertran, Patrick Le Fèvre, Iann C Gerber, Gilles Patriarche, Fabrice Oehler, Xavier Wallart, Abdelkarim Ouerghi

The growth of bilayers of two-dimensional (2D) materials on conventional 3D semiconductors results in 2D/3D hybrid heterostructures, which can provide additional advantages over more established 3D semiconductors while retaining some specificities of 2D materials. Understanding and exploiting these…

La spectroscopie térahertz: électrons et vibrations

Sarah Houver, Sophie Eliet Eliet-Barois, Pascale Roy, Romain Peretti

Les progrès technologiques ces dernières décennies ont fait croître de façon exponentielle l’utilisation de la spectroscopie TéraHertz. Cette gamme spectrale (1 THz = 1012 Hz) permet de sonder et caractériser les phénomènes physiques à basse énergie, où de nombreux processus élémentaires dans la…

Bound States in the Continuum and Induced Resonances in a Simple Plasmonic Waveguide with Sensing Application

Yamina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

A Friedrich–Wintgen bound state in the continuum (FW-BIC) is of particular interest in the field of wave physics phenomena. It is induced via the destructive interference of two modes that belong to the same cavity. In this work, we analytically and numerically show the existence of FW-BIC in a T-…
