TL;DR: In this paper, the structural and optical properties of lattice-matching AlInN layers to GaN have been investigated and their specific use to realize nearly strain-free structures for photonic and electronic applications has been discussed.
Journal ArticleDOI
Impact of disorder on high quality factor III-V nitride microcavities
TL;DR: In this paper, a micron scale characterization of a monolithic GaN microcavity with lattice matched AlInN∕GaN distributed Bragg reflectors by means of a microtransmission setup is presented.
Journal ArticleDOI
High quality nitride based microdisks obtained via selective wet etching of AlInN sacrificial layers
D. Simeonov,Eric Feltin,A. V. Altoukhov,A. Castiglia,J.-F. Carlin,Raphaël Butté,Nicolas Grandjean +6 more
TL;DR: In this article, a technique for selective wet chemical etching of an AlInN sacrificial layer lattice-matched to GaN for the fabrication of air-gap photonic structures is presented.
Journal ArticleDOI
Complex behavior of biexcitons in GaN quantum dots due to a giant built-in polarization field
TL;DR: In this paper, the binding energy of single polar GaN/AlN quantum dots (QDs) grown by molecular beam epitaxy is analyzed by means of low-temperature microphotoluminescence.
Journal ArticleDOI
