Graphene nanotransistors for RF charge detection

E. Pallecchi, Q. Wilmart, A.C. Betz, S.H. Jhang, G. Fève, J.M. Berroir, Sylvie Lepilliet, Gilles Dambrine, H. Happy, B. Plaçais

We have studied the static and dynamical properties of a graphene microwave nanotransistor to be used as sensitive fast charge detectors. The channel consists of exfoliated graphene on SiO2 with a 120 nm long, 900-1500 nm wide top-gate deposited on 5 nm AlOx dielectric. The scattering parameters…

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…

Polarization properties of specular and dense multipath components in a large industrial hall

Isabelle Vin, Davy Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, M. Lienard, Luc Martens

This paper presents a comprehensive analysis of the polarization characteristics of specular and dense multipath components in a large industrial hall, based on frequency-domain channel sounding experiments at 1.3 GHz. The RiMAX maximum-likelihood estimator is used to extract the full-polarimetric…

UV and IR laser induced ablation of Al2O3/SiN:H and a-Si:H/SiN:H

T. Schutz-Kuchly, A. Slaoui, J. Zelgowski, A. Bahouka, M. Pawlik, Jean-Pierre Vilcot, E. Delbos, M. Bouttemy, R. Cabal

Experimental work on laser induced ablation of thin Al2O3(20 nm)/SiN:H (70 nm) and a-Si:H (20 nm)/SiN:H (70 nm) stacks acting, respectively, as p-type and n-type silicon surface passivation layers is reported. Results obtained using two different laser sources are compared. The stacks are…

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…

Two types of MEMS-based oscillating AFM probes

Zhuang Xiong, Estelle Mairiaux, Benjamin Walter, Marc Faucher, Lionel Buchaillot, Bernard Legrand

Most of the commercial Atomic Force Microscope ( AFM) oscillating probes are based on micro-scale cantilevers enabling measurement with pico-Newton force resolution in vacuum. However, the cantilever probes suffer from a degradation of both resonance frequency and quality factor when operating in…

Caractérisation diélectrique des matériaux de construction dans le domaine des hyperfréquences

M.D. Belrhiti, S. Bri, A. Nakheli, Ahmed Mamouni

Dans la littérature, une variété de techniques pour extraire les paramètres constitutifs est disponible. Ces techniques incluant les méthodes résonantes et non résonantes avec leurs avantages et inconvénients sont également discutées. La caractérisation des matériaux de construction à l'aide…

Métasurface absorbante parfaite à base de cubes ferroélectriques distribués aléatoirement

Véronique Sadaune, Ludovic Burgnies, Eric Lheurette, Jianping Hao, Didier Lippens

L'utilisation d'une structure périodique de cubes de BaSrTiO3 interfacée avec une surface métallique par un fin film diélectrique permet d'obtenir une absorption proche de 100% à la fréquence de résonance de Mie magnétique. Cette absorption reste élevée pour un angle d'incidence…
