Seeded growth of HgTe nanocrystals for shape control and their use in narrow infrared electroluminescence

Yoann Prado, Junling Qu, Charlie Gréboval, Corentin Dabard, Prachi Rastogi, Audrey Chu, Adrien Khalili, Xiang Zhen Xu, Christophe Delerue, Sandrine Ithurria, Emmanuel Lhuillier

HgTe colloidal nanocrystals (NCs) have become a promising building block for infrared optoelectronics. Despite their cubic zinc blende lattice, HgTe NCs tend to grow in a multipodic fashion, leading to poor shape and size control. Strategies to obtain HgTe NCs with well-controlled sizes and shapes…

Suivi, détection et caractérisation d’un front de lixiviation par techniques destructives et non destructives

Charles Ciccarone, Bogdan Piwakowski, Frédéric Skoczylas, Jean-Marie Henault

L’objectif du travail présenté est la détection, la caractérisation et le suivi d’un front de lixiviation sur une structure en béton. Pour cela, les conditions de lixiviations in situ ont été reproduites sur des éprouvettes en laboratoire, et la détection du phénomène recherché a été conduite en…

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…

Trilayer conducting polymer transduction: device physics, modeling, and simulation

Sébastien Grondel, Sofiane Ghenna, Caroline Soyer, Eric Cattan, John D.W. Madden, Ngoc Tan Nguyen

Modelling trilayer conducting polymer is still challenging as it exhibits interrelated coupled multiscale and non-linear characteristics. Therefore, this work proposes to review the underlying electro-chemo-mechanical principles in ultrathin PEDOT trilayer ionic conducting polymers based upon…
