Integrated measurement platform for thermal conductivity measurements in thin-film crystalline silicon and silicon-germanium

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Thermoelectric conversion requires materials with low thermal conductivity k high electrical conductivity s and thermopower P. Performance of thermoelectric material is evaluated by the zT=P^2sT/k figure-of-merit. Bi2Te3 or Sb2Te3 are usually used near room temperature but they are harmful,…

Phosphorus-hyperdoped Si nanocrystals : a model for localized surface plasmon resonance

X. Pi, Christophe Delerue

It has been recently realized that semiconductor nanocrystals can be doped with point defects or impurities up to a very high level, sometimes above the bulk solubility limit. In parallel, hyperdoping has also emerged as a promising means to change the electrical and optical properties of Si. In…

Blind digital modulation identification for time-selective MIMO channels

Sofiane Kharbech, Iyad Dayoub, Marie Zwingelstein, Eric Pierre Simon, Kais Hassan

This paper addresses the problem of blind digital modulation identification in time-selective Multiple-Input Multiple-Output channels. Our objective is to recognize modulation schemes in highly-mobile communication environments, for military or high-speed railway applications, without signal…

Enhancing LSPR sensitivity of Au gratings through graphene coupling to Au film

Thomas Maurer, Rana Nicolas, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

A particular interesting plasmonic system is that of metallic nanostructures interacting with metal films. As the localized surface plasmon resonance (LSPR) behavior of gold nanostructures (Au NPs) on the top of a gold thin film is exquisitely sensitive to the spacer distance of the film-Au NPs, we…

F center in lithium fluoride revisited : comparison of solid-state physics and quantum-chemistry approaches

Ferenc Karsai, Paul Tiwald, Robert Laskowski, Fabien Tran, David Koller, Stefanie Gräfe, Joachim Burgdörfer, Ludger Wirtz, Peter Blaha

We revisit the theoretical description of the F color center in lithium fluoride employing advanced complementary ab initio techniques. We compare the results from periodic supercell calculations involving density-functional theory (DFT) and post-DFT techniques with those from the embedded-cluster…

Effect of passivation on microwave power performances of AlGaN/GaN/Si HEMTs

H. Mosbahi, M. Charfeddine, M. Gassoumi, H. Mejri, Christophe Gaquière, Bertrand Grimbert, M.A. Zaidi, H. Maaref

This paper reports on the use of plasma assisted molecular beam epitaxy of AlGaN/GaN high electron mobility transistors (HEMTs) grown on silicon substrate. Surface passivation effects on AlGaN/GaN HEMTs were studied using SiO2/SiN dielectric layers grown by plasma enhanced chemical vapor deposition…

Mechanical damage assessment of polymer-matrix composites using active infrared thermography

Walid Harizi, S. Chaki, Gérard Bourse, Mohamed Ourak

The present work uses an active form of the infrared (IR) thermography technique for monitoring and characterization of the damage of glass fibers reinforced Polymer-Matrix Composites (PMCs) following an experimental protocol based on a monotonic tensile test with constant stress steps. The active…

CW Radar for Monitoring Water-to-Cellular Concrete

Kamel Haddadi, Tuami Lasri

The physical deterioration of concrete structures is mainly caused by their moisture content. Consequently, methods dedicated to contactless, non-destructive and real-time monitoring of moisture content levels are required to control the deterioration of buildings. In this study, we propose an…
