Design and fabrication of uni-travelling carrier (UTC) photodiode based on InxGa1-xN semiconductors

Bandar Alshehri, Karim Dogheche, P.I. Seetoh, J.H. Teng, S.J. Chua, Didier Decoster, El Hadj Dogheche

This work is focused both on InxGa1-xN single-layer and InxGa1-xN/GaN multilayered structures, with high Indium content (x>35%). In this study, InGaN/GaN films are epitaxially grown on sapphire substrates by metalorganic chemical vapor deposition (MOCVD). The microstructure of GaN and InxGa1-xN…

Mécanisme de transport dans des jauges de contraintes à nanoparticules colloïdales

Moussa Biaye, Heinrich Diesinger, Nicolas Decorde, Jérémie Grisolia, Benoit Viallet, Laurence Ressier, Thierry Melin

Les écrans tactiles envahissent notre quotidien (smartphones, tablettes ...). Dans ce travail, l'objectif est de caractériser des surfaces tactiles résistives basées sur le transport à travers des couches autoassemblées de nanoparticules (NPs) métalliques. Il s'agit d'utiliser la…

Optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue, Ali Al-Otaify, David J. Binks, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach

HgTe nanocrystals presently receive growing interest because the negative band gap in bulk HgTe enables tunability of the gap from the infrared to the near infrared in quantum dots thanks to the quantum confinement. Therefore we propose a tight-binding model of HgTe which gives an accurate band…

All optical method for investigation of spin and charge transport in semiconductors : combination of spatially and time-resolved luminescence

Fabian Cadiz, Philippe Barate, D. Paget, Denis S Grebenkov, J.P. Korb, A.C.H. Rowe, Thierry Amand, S. Arscott, Emilien Peytavit

A new approach is demonstrated for investigating charge and spin diffusion as well as surface and bulk recombination in unpassivated doped semiconductors. This approach consists in using two complementary, conceptually related, techniques, which are time-resolved photoluminescence (TRPL) and…

Speech communication

Nicolas Côté, Jens Berger

The goal of any speech service is the transmission and/or processing of speech signals. In this chapter we discuss the Quality of Experience (QoE) of speech communication systems, including networks, speech processing applications and terminals. We then give an overview of the methods employed to…

Magneto-transport subband spectroscopy in InAs nanowires

Florian Vigneau, Vladimir Prudkovskiy, Ivan Duchemin, Walter Escoffier, Philippe Caroff, Yann-Michel Niquet, Renaud Leturcq, Michel Goiran, Bertrand Raquet

We report on magnetotransport measurements in InAs nanowires under a large magnetic field (up to 55 T), providing a spectroscopy of the one-dimensional electronic band structure. Large modulations of the conductance mediated by a control of the Fermi energy reveal the Landau fragmentation, carrying…
