Alternative and low-cost technique to transfer III-V DHBT transistors onto Si-HR using Cu-Cu bonding for sub-THz power amplification for 6G

Jihed Derouiche, Abdelmalek Zemour, Malek Zegaoui, Yannick Roelens, Pascal Chevalier, Mohammed Zaknoune

This study introduces the preparation of a future transferred InP double heterojunction bipolar transistor (DHBT) on a high-resistivity silicon substrate. Our approach employs copper (Cu) as a thermal heat sink and chosen for its excellent thermal conductivity, which will make possible efficient…

Fortran Package Manager fpm

Vincent Magnin

A l'instar d'autres langages tels que Rust, le langage Fortran dispose désormais d'un gestionnaire de paquets faisant également office d'outil de construction de projet : fpm (Fortran Package Manager). Cet outil est développé par la communauté Fortran-lang.org.

Manufacture of fast-charging 3D hybrid micro-capacitors for energy autonomy of miniaturised electronic components, Fabrication de micro-condensateurs hybrides 3D à charge rapide pour l'autonomie énergétique de composants électroniques miniaturisés

Cédric Teyssédou

On-board electronics currently suffer from a severe lack of energy autonomy. Our children's drones have limited autonomy of several tens of minutes and our energy-hungry mobile phones are recharged daily. As soon as the radio frequency resources of our smartphones are activated (WIFI,…, L'électronique embarquée souffre à ce jour d'un manque cruel d'autonomie énergétique. Les drones de nos enfants ont une autonomie limitée de plusieurs dizaines de minutes et nos téléphones mobiles très énergivores sont rechargés quotidiennement. Dès lors que les ressources…

Soft Fault Diagnosis in a Communication Cable using a Transferometry-Based Method

Ameer Ahmadie, Virginie Degardin, Vincent Cocquempot

This paper aims to detect and locate a soft fault, i.e. a physical degradation, in unshielded twisted pair cables used for data transmission in a networked control system (NCS). The proposed approach is based on the analysis of the transmission coefficient (TC) in the time domain for both nofault…

Exploring Quantum Analogies: Superradiance, Bipartite Correlations, and static Bell Tests in Pilot-Wave Hydrodynamics

Konstantinos Papatryfonos, Louis Vervoort, Mélanie Ruelle, Corentin Bourdiol, André Nachbin, Valeri Frumkin, Matthieu Labousse, John W M Bush

Since its discovery in 2005, the hydrodynamic pilot-wave system has provided a macroscopic realization of wave-particle duality, reproducing an increasing number of quantum-like effects. A key question is how closely particle-particle correlations in this classical system can mimic those at the…

Unique characteristics of the electronic and optical properties of HgTe nanocrystals

Antoine Hage, Christophe Delerue

HgTe is a semi-metallic material with unconventional electronic properties compared to the usual III-V or II-VI semiconductors, characterized by a negative bandgap, band inversion and topological insulator properties under the action of quantum confinement. How do these unique characteristics…
