Deep structural analysis of novel BGaN material layers grown by MOVPE

S. Gautier, G. Patriarche, T. Moudakir, M. Abid, G. Orsal, K. Pantzas, David Troadec, A. Soltani, L. Largeau, O. Mauguin, A. Ougazzaden

BGaN ternary alloys with 0.7% and 1.7% boron grown on GaN/sapphire template substrates by metalorganic vapour phase epitaxy (MOVPE) have been investigated through HAADF-STEM. At low boron content, 0.7%, no compositional fluctuations were observed with XRD or STEM measurements. Photoluminescence at…

Alpha-stable interference modeling and Cauchy receiver for an IR-UWB ad hoc network

Hamza El Ghannudi, Laurent Clavier, Nourddine Azzaoui, François Septier, Paul-Alain Rolland

In this paper we investigate ad hoc networks based on impulse radio ultra wideband. Due to multiple access, the interference distribution is not Gaussian. One important reason for errors is the presence of close interferers generating pulse collision. However such events are rare and we propose an…

Thermal instability of silicon-on-insulator thin films measured by low-energy electron microscopy

E. Bussmann, F. Cheynis, Frédéric Leroy, P. Muller

Using low-energy electron microscopy (LEEM), we investigate the ultrahigh vacuum annealing of silicon-on-insulator (SOI) samples capped by a chemically-prepared oxide layer. Consistent with previous reports: (1) for T > 750 • C, the capping-oxide decomposes by void nucleation and growth, then (2…

Dispositifs fluidiques de contrôle actif d’écoulements à base de microsystèmes magnéto-électro-mécanique (MMEMS) : (conception, réalisation, tests), Flow control fluidic actuators based on magnetic micro-electro-mechanical systems (MMEMS) : (design, fabrication, tests)

Romain Viard

Dans ce mémoire, une étude des conditions de contrôles d’écoulements aérodynamiques par des réseaux de générateurs de tourbillons fluidiques pulsés est menée pour établir un cahier des charges des micro-actionneurs instrumentés de faible coût, indispensables à la réalisation de ce type de contrôle…, This thesis starts with a study of aerodynamic flow control conditions by arrays of pulsed fluidic vortex generators. Detailed specifications are synthesised for the conception of low cost, sensors equipped, micro-actuators required to manage industrial scale active flow control experiments.…

Composants pour la génération et la détection d'impulsion térahertz, Components for generating and detecting terahertz pulses

Olivier Offranc

Le domaine de fréquences térahertz fait la liaison entre le monde des transistors et des lasers. Malgré les nombreuses applications possibles, il n'existe pas, à l'heure actuelle, de source térahertz compacte fonctionnant à température ambiante. De même, pour la détection d'…, The terahertz frequency range makes the connection between the world of transistors and lasers. Despite the many potential applications, today there is not compact terahertz source operating at room temperature. Similarly, for detection of terahertz pulses, there is not really satisfying systems…

Numerical simulations for a quantitative analysis of AFM electrostatic nanopatterning on PMMA by Kelvin force microscopy

Etienne Palleau, Laurence Ressier, Lukasz Borowik, Thierry Melin

Electrostatic nanopatterning of electret thin films by atomic force microscopy (AFM) has emerged as an alternative efficient tool for the directed assembly of nano-objects on surfaces. High-resolution charge imaging of such charge patterns can be performed by AFM-based Kelvin force microscopy (KFM…

100 nm period grating by high-index phase-mask immersion lithography

Yannick Bourgin, Yves Jourlin, Olivier Parriaux, Anne Talneau, Svetlen Tonchev, Colette Veillas, P. Karvinen, Nicolas Passilly, Ahmad Md Zain, R.M. de La Rue, Jurgen van Erps, David Troadec

The interferogram of a high index phase mask of 200 nm period under normal incidence of a collimated beam at 244 nm wavelength with substantially suppressed zeroth order produces a 100 nm period grating in a resist film under immersion. The paper describes the phase mask design, its fabrication,…
