High Breakdown Field and Low Trapping Effects up to 1400 V in Normally Off GaN‐on‐Silicon Heterostructures

Idriss Abid, Youssef Hamdaoui, Jash Mehta, F Medjdoub

In this study, we report on the development of a fully normally-off high electron mobility transistor (HEMT) gallium nitride on silicon (GaN-on-Si) heterostructures designed for high voltage operation. The normally-off configuration was achieved by means of a p-gallium nitride (p-GaN) cap layer…

CRC-Based Correction of Multiple Errors Using an Optimized Lookup Table

Vivien Boussard, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

In this paper, we propose a new approach to perform multiple error correction in wireless communications over error-prone networks. It is based on the cyclic redundancy check syndrome, using an optimized lookup table that avoids performing arithmetic operations. This method is able to achieve the…

Picosecond acoustics versus tape adhesion test: Confrontation on a series of similar samples with a variable adhesion

A. Vital-Juarez, L. Roffi, J.-M. Desmarres, Arnaud Devos

A large number of methods have been developed to characterize the adhesion of a thin film to a substrate. Among them, tape test is still one of the most popular methods. Acoustic waves and especially ultra-high frequency acoustic waves are also sensitive to adhesion defects as they affect the way…

Unstationary dynamics of drops subjected to MHz-surface acoustic waves modulated at low frequency

Philippe Brunet, Michael Baudoin

In the present work, we investigate the unstationary dynamics of sessile droplets subjected to high-frequency surface acoustic waves modulated at a lower frequency close to the first inertio-capillary resonance mode of the drop. Under the action of both acoustic streaming and radiation pressure,…

De la théorie à la pratique dans l’enseignement du traitement du signal : initiation à la recherche

Lynda Chehami, Nikolay Smagin, Jamal Assaad, Pierre Campistron, Frédéric Jenot, Emmanuel Moulin

Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la…

Optimized ohmic contacts for InAlGaN/GaN HEMTs

Pierre Ruterana, Marie Pierre Chauvat, Magali Morales, Farid Medjdoub, Piero Gamarra, Christian Dua, Sylvain Delage

In this work, we have carried out a detailed transmission electron microscopy investigation on ohmic contacts in InAl GaN/GaN high electron mobility transistors consisting of Ti/Al/Ni/Au deposited by evaporation electron beam followed by a rapid thermal annealing at 875°C for 30s under N2…

Optomechanical Hot-Spots in Metallic Nanorod–Polymer Nanocomposites

Thomas Vasileiadis, Adnane Noual, Yuchen Wang, Bartlomiej Graczykowski, Bahram Djafari-Rouhani, Shu Yang, George Fytas

Plasmonic coupling between adjacent metallic nanoparticles can be exploited for acousto-plasmonics, single-molecule sensing, and photochemistry. Light absorption or electron probes can be used to study plasmons and their interactions, but their use is challenging for disordered systems and colloids…

10. Incremental learning of convolutional neural networks in bioinformatics

Wafa Mousser, Salima Ouadfel, Abdelmalik Taleb-Ahmed

In recent years, convolutional neural networks (CNNs) have been widely used in various computer visual recognition tasks and then extensively applied for medical images, particularly for computer-aided diagnosis. Despite this success, CNNs suffer from a catastrophic forgetting issue, making it…

Pairing cells of different sizes in a microfluidic device for immunological synapse monitoring

Faruk Azam Shaik, Clara Lewuillon, Aurélie Guillemette, Bahram Ahmadian, Carine Brinster, Bruno Quesnel, Dominique Collard, Yasmine Touil, Loïc Lemonnier, Mehmet Tarhan

Analyzing cell–cell interaction is essential to investigate how immune cells function. Elegant designs have been demonstrated to study lymphocytes and their interaction partners. However, these devices have been targeting cells of similar dimensions. T lymphocytes are smaller, more deformable, and…
