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…

Enhanced radiative efficiency in GaN nanowires grown on sputtered TiN: effects of surface electric fields
T. Auzelle, M. Azadmand, T. Flissikowski +8
GaN nanowires grown by molecular beam epitaxy generally suffer from dominant nonradiative recombination, which is believed to originate from point defects. To suppress the formatio…

Absence of quantum-confined Stark effect in GaN quantum disks embedded in (Al,Ga)N nanowires grown by molecular beam epitaxy
C. Sinito, P. Corfdir, C. Pfüller +14
Several of the key issues of planar (Al,Ga)N-based deep-ultraviolet light emitting diodes could potentially be overcome by utilizing nanowire heterostructures, exhibiting high stru…
