Journal ArticleDOI
Fine structure of the exciton in a single asymmetric CdTe quantum dot
TL;DR: In this paper, a mixing of dark and bright excitons is observed for localization sites that present a large zero-field splitting, which allows a direct estimate of the electron and hole g-factors and of the isotropic exchange energy for strongly localized heavy-hole excITons.
Journal ArticleDOI
Microgun-pumped semiconductor laser
TL;DR: In this article, the authors demonstrate the feasibility of a microgun-pumped semiconductor laser that operates in a quasi-cw mode with 5 μs pulses at 2 kHz with CdTe−CdMnTe graded index separate confinement quantum-well heterostructures.
Journal ArticleDOI
Carrier depletion and exciton diffusion in a single ZnO nanowire.
TL;DR: Carrier depletion and transport in a single ZnO nanowire Schottky device have been investigated at 5 K, using cathodoluminescence measurements, found to increase linearly with the reverse bias.
Journal ArticleDOI
Study of isolated cubic GaN quantum dots by low-temperature cathodoluminescence
J.P. Garayt,Jean-Michel Gérard,F. Enjalbert,L. Ferlazzo,S. Founta,E. Martinez-Guerrero,Fabian Rol,Daniel Araujo,R.T. Cox,Bruno Daudin,Bruno Gayral,Le Si Dang,Henri Mariette +12 more
TL;DR: In this paper, a single dot spectroscopy of cubic GaN/AlN self-assembled quantum dots is presented, showing that the phonon sideband contribution in this emission reveals the importance of the acoustic phonon broadening mechanism which controls the exciton dephasing and may impose the real limits to the optical properties of GaN single QDs emission.
Journal ArticleDOI
GaN quantum dots doped with Tb
Yuji Hori,T. Andreev,D. Jalabert,Eva Monroy,Le Si Dang,Bruno Daudin,Mitsuhiro Tanaka,Osamu Oda +7 more
TL;DR: In this paper, Eu-doped GaN quantum dots embedded in AlN have been investigated and the signature of the Eu short-range environment for several samples was compared.
