Journal ArticleDOI
Molecular-beam epitaxial growth and characterization of quaternary III–nitride compounds
Eva Monroy,Noelle Gogneau,F. Enjalbert,Frédéric Fossard,D. Jalabert,Edith Bellet-Amalric,Le Si Dang,Bruno Daudin +7 more
TL;DR: In this paper, the growth and characterization of quaternary AlGaInN compounds by plasma-assisted molecular beam epitaxy is described, where a monolayer of In segregates at the growth front.
Journal ArticleDOI
Synchronized and desynchronized phases of exciton-polariton condensates in the presence of disorder
A. Baas,Konstantinos G. Lagoudakis,Maxime Richard,Régis André,Le Si Dang,Benoit Deveaud-Plédran +5 more
TL;DR: Condensation of exciton polaritons in semiconductor microcavities takes place despite in-plane disorder, and in the case of strong disorder, several non-phase-locked condensates can be evidenced.
Journal ArticleDOI
Probing exciton localization in nonpolar GaN/AlN quantum dots by single-dot optical spectroscopy
Fabian Rol,S. Founta,H. Mariette,Bruno Daudin,Le Si Dang,Joël Bleuse,David Peyrade,Jean-Michel Gérard,Bruno Gayral +8 more
TL;DR: In this article, an optical spectroscopy study of nonpolar quantum dots by time-resolved photoluminescence and by microphotoluminecence is presented, which indicates that the carriers are laterally localized on a scale that is much smaller than the quantum dot size.
Journal ArticleDOI
Light emitting diodes based on GaN core/ shell wires grown by MOVPE on n-type Si substrate
A.-L. Bavencove,Damien Salomon,Matthieu Lafossas,B. Martin,Amélie Dussaigne,F. Levy,B. André,Pierre Ferret,Christophe Durand,Joël Eymery,Le Si Dang,P. Gilet +11 more
TL;DR: In this article, the fabrication of light emitting diodes (LEDs) based on GaN core/shell wires on conductive substrates by metal organic vapour phase epitaxy is described.

One-dimensional ZnO exciton polaritons with negligible thermal broadening at room temperature
Aurelien A. P. Trichet,Liaoxin Sun,Goran Pavlovic,Nikolay A. Gippius,Guillaume Malpuech,Wei Xie,Zhanghai Chen,Maxime Richard,Le Si Dang +8 more
TL;DR: In this article, the authors showed that excitons in semiconductors can be totally decoupled from the phonon bath, even at room temperature, thanks to their strong interaction with photons.
