Characteristics of the surface microstructures in thick InGaN layers on GaN

Y. El Gmili, G. Orsal, K. Pantzas, A. Ahaitouf, T. Moudakir, S. Gautier, G. Patriarche, David Troadec, Jean-Paul Salvestrini, A. Ougazzaden

This paper focuses on a comparative study of optical, morphological, microstructural and microcompositional properties of typical InGaN samples which exhibit V-defects but also two additional surface defects features, referred to as inclusion#1 (Ic1) and inclusion#2 (Ic2). HR-XRD, AFM, SEM, STEM…

Time-reversal UWB positioning beacon for railway application

B. Fall, F. Elbahhar, M. Heddebaut, Atika Rivenq

This paper studies a new positioning beacon for railway transport using Ultra Wideband (UWB) radio and Time Reversal (TR) techniques. UWB radio has the potential to offer a good level of performance in terms of localization accuracy. Time Reversal channel pre-filtering facilitates signal detection…

Focused ion beam Ga3+ for the realization of piezoelectric PZT nano structures

Denis Remiens

Piezoelectric nano-structures (islands of dimensions in the lateral size range 50-500 nm) have been fabricated by Focused Ga3+ Ion Beam (FIB) etching on PbZr0.54Ti0.46O3 thin films obtained by magnetron sputtering. The degradation induced by the etching process is investigated through the evolution…

The effect of long-term working memory through personalization applied to free recall : Uncurbing the primacy-effect enthusiasm

Alessandro Guida, Doriane Gras, Y. Noel, Olivier Le Bohec, Christophe Quaireau, Stéphane Nicolas

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862-896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate…

Modeling of Ga1-xInxAs1-y-zNySbz/GaAs quantum well properties for near-infrared lasers

Abdelkader Aissat, Said Nacer, Farid Ykhlef, Jean-Pierre Vilcot

The aim of this work is to model the properties of GaInAsNSb/GaAs compressively strained structures. Indeed, Ga1−xInxAs1−y−zNySbz has been found to be a potentially superior material to GaInAsN for long wavelength laser dedicated to optical fiber communications. Furthermore, this material can be…
