Crystal phases in III-V nanowires : from random toward engineered polytypism

Philippe Caroff, Jessica Bolinsson, Jonas Johansson

III-V nanowires (NWs) are promising for a wide range of applications, ranging from optics to electronics, energy, and biological sensing. The structural quality of NWs is of paramount importance for the performance of such future NW-based devices. Random structural defects and polytypism occur…

Mise en oeuvre d'architectures de transcodage vidéo H.264/AVC et SVC, Implementation of H.264/AVC and SVC transrating architectures

Christophe Deknudt

Les travaux présentés dans ce manuscrit de thèse se sont déroulés majoritairement dans le cadre du projet TOSCANE dont l’objectif était d’optimiser les transmissions de flux vidéo haute définition (HD). Pour cela, deux types d’architectures de transcodage à complexité réduite des flux H.264/AVC…, The works presented in this thesis are mainly part of the French ANR TOSCANE project which aims to optimize high definition video transmission. We propose two types of low complexity transrating architectures for H.264/AVC streams to adapt video bitrate to channel bandwidth. The first transrating…

Investigation of the negative differential resistance reproducibility in AlN/GaN double barrier resonant tunneling diodes in DC operation

Mohamed Boucherit, Ali Soltani, D. Deresmes, Maxime Berthe, Eva Monroy, Michel Rousseau, Jean-Claude de Jaeger

AlN/GaN double-barrier resonant tunnelling diodes were grown by molecular beam epitaxy on GaN/sapphire template and processed into mesa diameters from 2 μm to 4 μm. The current-voltage characteristics were carried out in direct current operation and under-high vacuum. A sharp negative differential…

Efficient photogeneration of charge carriers in silicon nanowires with a radial doping gradient

D.H.K. Murthy, T. Xu, W. H. Chen, J. Houtepen A., T.J. Savenije, L.D.A. Siebbeles, J.P. Nys, Christophe Krzeminski, B. Grandidier, Didier Stiévenard, Philippe Pareige, F. Jomard, Gilles Patriache, O.I. Lebedev

From electrodeless time-resolved microwave conductivity measurements, the efficiency of charge carrier generation, their mobility, and decay kinetics on photo-excitation were studied in arrays of Si nanowires grown by the vapor-liquid-solid mechanism. A large enhancement in the magnitude of the…

Fluorescent molecular nanocrystals anchored in sol-gel thin films: a label-free signalization function for biosensing applications

Emilie Dubuisson, Sabine Szunerits, Maria Bacia, Robert Bernard Pansu, Alain Ibanez

A DNA sensor based on highly fluorescent and photostable molecular nanocrystals has been investigated. These nanocrystals are confined in a sol-gel thin film by a simple one-step process. After controlled dissolution of the sol-gel thin film layer-by-layer, nanocrystals emerge from the silicate…
