Self-assembly of well-separated AlN nanowires directly on sputtered metallic TiN films
Mani Azadmand, Tomas Auzelle, Jonas Lähnemann +7
We demonstrate the self-assembled formation of AlN nanowires by molecular beam epitaxy on sputtered TiN films on sapphire. This choice of substrate allows growth at an exceptionall…
Electroluminescence and current-voltage measurements of single (In,Ga)N/GaN nanowire light-emitting diodes in the nanowire ensemble
David van Treeck, Johannes Ledig, Gregor Scholz +7
We present the combined analysis of the electroluminescence (EL) as well as the current-voltage (I-V) behavior of single, freestanding (In,Ga)N/GaN nanowire (NW) light-emitting dio…
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…
Determination of the carrier diffusion length in GaN from cathodoluminescence maps around threading dislocations: fallacies and opportunities
Vladimir M. Kaganer, Jonas Lähnemann, Carsten Pfüller +3
We investigate, both theoretically and experimentally, the drift, diffusion, and recombination of excitons in the strain field of an edge threading dislocation intersecting the GaN…
Top-down fabrication of ordered arrays of GaN nanowires by selective area sublimation
Sergio Fernández-Garrido, Thomas Auzelle, Jonas Lähnemann +3
We demonstrate the top-down fabrication of ordered arrays of GaN nanowires by selective area sublimation of pre-patterned GaN(0001) layers grown by hydride vapor phase epitaxy on A…
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…
