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…

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…

Novel heterostructured Ge nanowires based on polytype transformation

Laetitia Vincent, Gilles Patriarche, Géraldine Hallais, Charles Renard, Cyrille Gardès, David Troadec, Daniel Bouchier

We report on a strain-induced phase transformation in Ge nanowires under external shear stresses. The resulted polytype heterostructure may have great potential for photonics and thermoelectric applications. ⟨111⟩-oriented Ge nanowires with standard diamond structure (3C) undergo a phase…

Mécanisme de transport dans des jauges de contraintes à nanoparticules colloïdales

Moussa Biaye, Heinrich Diesinger, Nicolas Decorde, Jérémie Grisolia, Benoit Viallet, Laurence Ressier, Thierry Melin

Les écrans tactiles envahissent notre quotidien (smartphones, tablettes ...). Dans ce travail, l'objectif est de caractériser des surfaces tactiles résistives basées sur le transport à travers des couches autoassemblées de nanoparticules (NPs) métalliques. Il s'agit d'utiliser la…

Efficient reduction of thermal conductivity in silicon using phononic-engineered membranes

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

Phononic crystals (PC) have been a remarkably active research field for more than two decades [1]. The principle of Bragg reflection on an artificial crystal-like structure leading to additional spectral (band gaps) and refractive (negative refraction, anisotropy) properties is scalable in any…

Design and fabrication of uni-travelling carrier (UTC) photodiode based on InxGa1-xN semiconductors

Bandar Alshehri, Karim Dogheche, P.I. Seetoh, J.H. Teng, S.J. Chua, Didier Decoster, El Hadj Dogheche

This work is focused both on InxGa1-xN single-layer and InxGa1-xN/GaN multilayered structures, with high Indium content (x>35%). In this study, InGaN/GaN films are epitaxially grown on sapphire substrates by metalorganic chemical vapor deposition (MOCVD). The microstructure of GaN and InxGa1-xN…

Interferometric Near-field Microwave Microscopy Platform for Electromagnetic Micro-analysis

Kamel Haddadi, Jaouad Marzouk, Sijia Gu, S. Arscott, Gilles Dambrine, Tuami Lasri

We report an original near-field microwave microscope based on an interferometric technique for dielectric characterization in liquid media. The instrumentation combines a vector network analyzer, an interferometry-based matching network and dedicated evanescent microstrip probes fabricated in…
