High-temperature growth of GaN nanowires by molecular beam epitaxy: toward the materials quality of bulk GaN
J. K. Zettler, C. Hauswald, P. Corfdir +5
In molecular beam epitaxy, the spontaneous formation of GaN nanowires on Si(111) substrates at elevated temperatures is limited by the long incubation time that precedes nanowire n…
Molecular Beam Epitaxy of GaN Nanowires on Epitaxial Graphene
Sergio Fernández-Garrido, Manfred Ramsteiner, Guanhui Gao +10
We demonstrate an all-epitaxial and scalable growth approach to fabricate single-crystalline GaN nanowires on graphene by plasma-assisted molecular beam epitaxy. As substrate, we e…
Observation of dielectrically confined excitons in ultrathin GaN nanowires up to room temperature
Johannes K. Zettler, Pierre Corfdir, Christian Hauswald +10
The realization of semiconductor structures with stable excitons at room temperature is crucial for the development of excitonics and polaritonics. Quantum confinement has commonly…
Drastic effect of sequential deposition resulting from flux directionality on the luminescence efficiency of nanowire shells
Hanno Küpers, Ryan B. Lewis, Pierre Corfdir +6
Core-shell nanowire heterostructures form the basis for many innovative devices. When compound nanowire shells are grown by directional deposition techniques, the azimuthal positio…
Radius-Dependent Homogeneous Strain in Uncoalesced GaN Nanowires
G. Calabrese, D. van Treeck, V. M. Kaganer +6
We investigate the strain state of ensembles of thin and nearly coalescence-free self-assembled GaN nanowires prepared by plasma-assisted molecular beam epitaxy on Ti/AlO$_{3…
Coaxial GaAs/(In,Ga)As dot-in-a-well nanowire heterostructures for electrically driven infrared light generation on Si in the telecommunication O band
Jesús Herranz, Pierre Corfdir, Esperanza Luna +8
Core-shell GaAs-based nanowires monolithically integrated on Si constitute a promising class of nanostructures that could enable light emitters for fast inter- and intrachip optica…
