AlGaN channel high electron mobility transistors with regrown ohmic contacts

Idriss Abid, Jash Mehta, Yvon Cordier, Joff Derluyn, Stefan Degroote, Hideto Miyake, F Medjdoub

High power electronics using wide bandgap materials are maturing rapidly, and significantmarket growth is expected in a near future. Ultra wide bandgap materials, which have an even largerbandgap than GaN (3.4 eV), represent an attractive choice of materials to further push the performancelimits of...

Parasitic loop inductances reduction in the PCB layout in GaN-based power converters using S-parameters and EM simulations

Loris Pace, Nadir Idir, Thierry Duquesne, Jean-Claude de Jaeger

Due to the high switching speed of Gallium Nitride (GaN) transistors, parasitic inductances have significant impacts on power losses and electromagnetic interferences (EMI) in GaN-based power converters. Thus, the proper design of high-frequency converters in a simulation tool requires accurate...

Covid-19 recognition using ensemble-cnns in two new chest x-ray databases

Edoardo Vantaggiato, Emanuela Paladini, Fares Bougourzi, Cosimo Distante, Abdenour Hadid, Abdelmalik Taleb-Ahmed

The recognition of COVID-19 infection from X-ray images is an emerging field in the learning and computer vision community. Despite the great efforts that have been made in this field since the appearance of COVID-19 (2019), the field still suffers from two drawbacks. First, the number of available...

Development of micron sized photonic devices based on deep GaN etching

Karim Dogheche, Bandar Alshehri, Gilles Patriache, El Hadj Dogheche

In order to design and development efficient III-nitride based optoelectronic devices, technological processes require a major effort. We propose here a detailed review focussing on the etching procedure as a key step for enabling high date rate performances. In our reported research activity, dry...

Electric circuit model of microwave optomechanics

Xin Zhou, Dylan Cattiaux, Didier Theron, Eddy Collin

We report on the generic classical electric circuit modeling that describes standard single-tone microwave optomechanics. Based on a parallel RLC circuit in which a mechanical oscillator acts as a movable capacitor, derivations of analytical expressions are presented, including key features such as...

Toward an electroactive polymer-based soft microgripper

Chia-Ju Peng, Lauréline Seurre, Eric Cattan, Giao Tran Minh Nguyen, Cedric Plesse, Luc Chassagne, Barthélemy Cagneau

Grasping and manipulating objects on a microscale hold great promise, especially using mechanical structures made from soft materials that enable, for example, safe operations during micro-surgery. Soft robots should be preferred to manipulate micro-objects, but their adoption requires, inter alia...

Passive resonant sensors: trends and future prospects

Hamida Hallil, Corinne Dejous, Sami Hage-Ali, Omar Elmazria, Jérôme Rossignol, Didier Stuerga, Abdelkrim Talbi, Aurelien Mazzamurro, Pierre-Yves Joubert, Elie Lefeuvre

Sensors based on "resonance phenomenon" span a broad spectrum of important current applications including detection of biological and chemical agents, and measurements of physical quantities. Resonance phenomena occur with all types of waves: electromagnetic, optic, and acoustic. This...
