First demonstration of vertical AlGaN P-i-N diodes grown on silicon substrate for Next-Generation power electronics

Jash Mehta, Abdelkhalek Sefssafi, Antoine Barbier, Stephanie Rennesson, Fabrice Semond, Julien Brault, F Medjdoub

In this work, we report the first demonstration of quasi-vertical AlGaN PiN diodes grown directly on silicon substrates, paving the way toward high-performance, low-cost power electronics. GaN and AlGaN heterostructures were grown on 2-inch silicon wafers via molecular beam epitaxy. The AlGaN diode…

Proposed Experiments for Detecting Contextual Hidden Variables

Konstantinos Papatryfonos, Louis Vervoort

We propose two quantum experiments – modified Bell tests – that could detect contextual hidden variables underlying quantum mechanics. The experiments are inspired by hydrodynamic pilot-wave systems that mimic a wide range of quantum effects and exhibit a classical analog of contextuality. To…

Traitement de signaux neuronaux à base de réseaux de neurones à décharges optimisés pour accélérateurs neuromorphiques, Processing neural signal with spiking neural networks optimized for neuromorphic hardware

Alexis Melot

Les Interfaces Cerveau-Machine (ICM) reposent sur le tri de potentiels d'action pour décoder l'activité des neurones individuels, une méthode centrale pour des neuroprothèses et l'étude des circuits cérébraux. Avec l'amélioration des sondes neuronales incluant une densité…, Brain-Machine Interfaces (BMIs) depend on sorting action potentials (spike sorting) to decode individual neuron activity, an essential process in both neuroprosthetics and the study of neural circuits. Advances in neural probes, particularly the increased electrode density, have dramatically…

Exploring ultrasound for monitoring phospholipid content in edible oils

Safia Lemlikchi, Johan Carlson, Samir Hadjal, Mohammed Asmani, Hakim Djelouah

This study investigates the feasibility of using ultrasound to monitor phospholipid (PL) content in edible oils during refining, aiming to establish a reliable alternative or complementary method to conventional physico-chemical analyses. Ultrasonic measurements were performed on soybean oil…

Improving electrical contact of vertically aligned carbon nanotubes with bonding metals in thermocompression bonding through oxygen plasma treatment

Jianping Zou, Rongtao Jiang, Chong Wei Tan, Dominique Baillargeat, Philippe Coquet, Beng Kang Tay

Vertically aligned carbon nanotubes (VACNTs) are being widely studied due to their exceptional mechanical, electrical, and thermal properties. The application of thermocompression bonding (TCB) technique has positioned VACNTs as promising candidates for 3D heterogeneous integration, interconnects,…

Temperature-dependent electrostatic, linearity, and analog/RF performance of GaN HEMT

Sabrina Alam, Christophe Gaquiere, Mohammad Abdul Alim

Temperature has a major impact on the performance and reliability of high-frequency AlGaN/GaN HEMTs for high-power applications. Despite substantial research, these devices’ multi-bias behavior throughout a wide temperature range is still poorly understood. This study investigates DC, electrostatic…
