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…

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.…
