Mercury telluride colloidal quantum dots : electronic structure, size-dependent spectra, and photocurrent detection up to 12 µm

Sean E. Keuleyan, Philippe Guyot-Sionnest, Christophe Delerue, Guy Allan

HgTe colloidal quantum dots are synthesized with high monodispersivity with sizes up to ∼15 nm corresponding to a room temperature absorption edge at ∼5 μm. The shape is tetrahedral for larger sizes and up to five peaks are seen in the absorption spectra with a clear size dependence. The size range...

Impacts of bioremediation schemes for the mitigation of a low-dose anthracene contamination on free-living marine benthic nematodes

Haithem Louati, O. Ben Said, A. Soltani, Cristiana Cravo-Laureau, Hugues Preud'Homme, Robert Duran, P. Aïssa, E. Mahmoudi, O. Pringault

A microcosm experiment was used to examine (1) the effects of different bioremediation schemes on degradation of anthracene and the structure of free-living marine nematodes in a lightly contaminated (4.5 μg g -1) sediment from Bizerte lagoon and (2) the responses of the nematode community upon an...

Multilayer magnetostrictive structure based surface acoustic wave devices

Huan Zhou, Abdelkrim Talbi, Nicolas Tiercelin, Olivier Bou Matar

This study addresses the experimental and theoretical investigations of guided elastic waves propagation in piezo-magnetic multi-layered structure. The structure is composed of a 20 TbCo2(5nm)/ FeCo(5nm) nanostructured multi-layer deposited between two Aluminum (Al) Inter-Digitals Transducers...

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...

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...

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...

Simultaneous bandgaps in LiNbO3 phoxonic crystal slab

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik, Yan Pennec, Bahram Djafari-Rouhani, Vincent Laude

We study simultaneous photonic and phononic crystal slabs created in Z-cut lithium niobate membranes. Bandgaps for guided waves are identified using the three-dimensional finite element method (FEM). Three lattices are considered: the square, the hexagonal, and the honeycomb lattices. We...
