Control of local wetting by microscopic particles

Lizhong Mu, Harunori N. Yoshikawa, Daichi Kondo, Tetsuya Ogawa, Mayu Kiriki, Farzam Zoueshtiagh, Masahiro Motosuke, Toshihiro Kaneko, Ichiro Ueno

We perform experiments to investigate how particles of micro-meter size modify the wetting of a completely wettable solid surface. The motion of a macroscopic contact line (MCL) is observed to be altered in the region surrounding the particles. The MCL is accelerated locally by a single particle to...

Single channel 100 Gbit/s link in the 300 GHz band

Vinay Kumar Chinni, Philipp Latzel, Malek Zegaoui, Christophe Coinon, X. Wallart, Emilien Peytavit, Jean-Francois Lampin, Klaus Engenhardt, P. Szriftgiser, Mohammed Zaknoune, Guillaume Ducournau

We report on the achievement of single channel 100 Gbit/s transmission, using linear resonant cavity enhanced unitravelling carrier photodiodes and QAM-16 modulation format. The indoor wireless link has been validated for up to 100 Gbit/s and 280 GHz carrier frequency.

Improving performance of OFET by tuning occurrence of charge transport based on pentacene interaction with SAM functionalized contacts

Shuo Li, David Guérin, Kamal Lmimouni

Optimized pentacene thin film transistors have been achieved by two technological self-assembled monolayers (SAM) treatments, with surface modification of 3-octadecyltrichlorosilane (OTS) monolayer on SiO2 dielectric layer and 2,3,4,5,6-pentafluorobenzenethiol (PFBT) monolayer on gold source/drain...

Effect of graphene layer on the localized surface plasmon resonance (LSPR) and the sensitivity in periodic nanostructure

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

We study the interaction of gold nanoparticles with a graphene film. Graphene is used as a spacer, as thin as possible, between the gold nanoparticles and the detection dielectric medium, and one of the advantages of graphene is to protect the structure, which allows to avoid the oxidation of...

High-resolution THz gain measurements in optically pumped ammonia

Martin Mičica, Sophie Eliet, Mathias Vanwolleghem, Roman Motiyenko, Anastasia Pienkina, Laurent Margulès, Kamil Postava, Jaromír Pištora, Jean-Francois Lampin

This study is aimed at the evaluation of THz gain properties in an optically pumped NH$_3$ gas. NH$_3$ molecules undergo rotational-vibrational excitation by mid-infrared (MIR) optical pumping provided by a MIR quantum cascade laser (QCL) which enables precise tuning to the NH3 infrared transition...

Electric field tuning of magnetism in heterostructure of yttrium iron garnet film/lead magnesium niobate-lead zirconate titanate ceramic

Jianyun Lian, Freddy Ponchel, Nicolas Tiercelin, Ying Chen, Denis Remiens, Tuami Lasri, Genshui Wang, Philippe Pernod, Wenbin Zhang, Xianlin Dong

In this paper, the converse magnetoelectric (CME) effect by electric field tuning of magnetization in an original heterostructure composed of a polycrystalline yttrium iron garnet (YIG) film and a lead magnesium niobate-lead zirconate titanate (PMN-PZT) ceramic is presented. The magnetic...

Miniaturized Coplanar Waveguide for Nanostructured Magnetostrictive Multilayer Characterization

Abdelhatif El Fellahi, Aurélien Mazzamurro, Jean Claude Gerbedoen, Yannick Dusch, Olivier Bou Matar, Philippe Pernod, Abdelkrim Talbi, Nicolas Tiercelin

A miniaturized coplanar waveguide (CPW) on a Y-cut LiNbO3 substrate operating in Radio Frequency region (RF) is proposed for studying of magnetostrictive multi-layered structure. The structure is composed of a 14 × [TbCo2 (3.7 nm)/FeCo (4 nm)] nanostructured multi-layer. Using microtechnology...

Mechanical properties of porous silicon and oxidized porous silicon by nanoindentation technique

Souheyla Fakiri, Alex Montagne, Khadidja Rahmoun, Alain Iost, Katir Ziouche

A study of mechanical properties of mesoporous silicon (PS) is presented in this article. PS was prepared by electrochemical etching of a heavily doped P++ silicon wafer in a hydrofluoric acid electrolyte. The mechanical properties of PS and oxidized PS obtained by thermal treatment, were...

Conception and realization of highly selective band-pass filters in Ka-band built on thin polymer films

Mohammed El Gibari, Sara Bretin, Patrick Derval, S. Ginestar, Guillaume Lirzin, Hong Wu Li

A novel structure of high performance narrow band-pass filters on thin polymer film is reported in this paper. It's composed of two microstrip resonators placed between two via-free microstrip-grounded coplanar waveguide transitions. It combines therefore compactness, low-cost, fabrication...

An Added Value Alternative to RAIN RFID Items Characterization in Retail

Hadi Farhat, Plamen Iliev, Philippe Mariage, Nathalie Rolland

This paper deals with the difficulties of detecting UHF passive RFID tags in a RAIN RFID system implemented in a retail environment. The aim of this paper is to evolve from the notion of characterizing a tag to the approach of evaluating a tagged item in a system, in order to better understand the...
