Inkjet coplanar square monopole on flexible substrate for 60-GHz applications

Aimeric Bisognin, Julien Thielleux, Wei Wei, Diane Titz, Fabien Ferrero, Patrice Brachat, Gilles Jacquemod, Henri Happy, Cyril Luxey

In this letter, the design, fabrication, and measurement of a 60-GHz printed antenna with inkjet technology over a flexible substrate is presented. The antenna is a coplanar square monopole with omnidirectional radiation characteristics. We especially measured a 68% total efficiency and a maximum...

Microscopie champ proche aux fréquences térahertz

Gabriel Moreno

Ce travail de thèse porte sur l'étude et sur l'adaptation de la microscopie champ proche (s-SNOM) dans les bandes de fréquences moyen-infrarouge (3-15 μm) et terahertz (100 μm - 1 mm). Nous présentons les principales caractéristiques de cette technique de microscopie. Pour cela, une sonde...

Optimization of the optical properties of nanostructured silicon surfaces for solar cell applications

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini-Robbe, Tao Xu, Yannick Lambert, Yves Deblock, Marc Faucher, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping in solar cell. We present simulations on both the optical properties and the efficiency of micro pillars--MPs--or nanocones--NCs--silicon based solar cells together with measurements on their associated...

Electro-optic and converse-piezoelectric properties of epitaxial GaN grown on silicon by metal-organic chemical vapor deposition

Mireille Cuniot-Ponsard, Irma Saraswati, S.M. Ko, Mathieu Halbwax, Y.H. Cho, El Hadj Dogheche

We report the measurement of the (r13, r33) Pockels electro-optic coefficients in a GaN thin film grown on a Si(111) substrate. The converse piezoelectric (d33) and electro-absorptive coefficients are simultaneously determined. Single crystalline GaN epitaxial layers were grown with a AlGaN buffer...

Biostimulation as an attractive technique to reduce phenanthrene toxicity for meiofauna and bacteria in lagoon sediment

Haithem Louati, O.B. Said, A. Soltani, P. Got, Cristiana Cravo-Laureau, Robert Duran, P. Aissa, O. Pringault, E. Mahmoudi

A microcosm experiment was setup to examine (1) the effect of phenanthrene contamination on meiofauna and bacteria communities and (2) the effects of different bioremediation strategies on phenanthrene degradation and on the community structure of free-living marine nematodes. Sediments from...

[Invited] High frequency electronic devices : impact of beyond graphene materials

Henri Happy, D. Mele, Ivy Colambo, Mohamed Salah Khenissa, Mohamed Moez Belhaj, Emiliano Pallecchi, Abdelkarim Ouerghi, Dominique Vignaud, Gilles Dambrine

Considering graphene field effect transistors (GFETs), considerable efforts have been made during the recent years to reach impressive current gain cut-off frequency (ft) over 400 GHz. Unfortunately, for these devices, the maximum frequency of oscillation (fmax) remains under 100GHz. This deviation...

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic...

Effect of thickness and deposition rate on the structural and magnetic properties of evaporated Fe/Al thin films

M. Mebarki, A. Layadi, L. Kerkache, A. Benabbas, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

We report experimental results on the structural and magnetic properties of Fe thin films deposited by thermal evaporation onto polycrystalline Al substrates. The effect of thickness t (in the 76 to 431 nm range) and deposition rate are investigated. The texture, the strain, and the grain size...
