Quasi van der Waals Epitaxial Growth of GaAsSb Nanowires on Graphitic Substrate for Photonic Applications
Dingding Ren, Tron A. Nilsen, Julie S. Nilsen +6
III-V semiconductor nanowires are considered promising building blocks for advanced photonic devices. One of the key advantages is that the lattice mismatch can easily be accommoda…
Single-mode Near-infrared Lasing in a GaAsSb/GaAs Nanowire Superlattice at Room Temperature
Dingding Ren, Lyubomir Ahtapodov, Julie S. Nilsen +7
Semiconductor nanowire lasers can produce guided coherent light emission with miniaturized geometry, bringing about new possibility for a variety of applications including nanophot…
Symmetries and optical transitions of hexagonal quantum dots in GaAs/AlGaAs nanowires
Guro K. Svendsen, Johannes Skaar, Helge Weman +1
We investigate the properties of electronic states and optical transitions in hexagonal GaAs quantum dots within AlGaAs nanowires. Such dots are particularly interesting due to the…
Investigations of Bragg reflectors in nanowire lasers
Guro Kristin Svendsen, Helge Weman, Johannes Skaar
The reflectivity of various Bragg reflectors in connection to waveguide structures, including nanowires, has been investigated using modal reflection and transmission matrices. A s…
Model for reflection and transmission matrices of nanowire end facets
Guro K. Svendsen, Helge Weman, Johannes Skaar
Nanowires show a large potential for various electrooptical devices, such as light emitting diodes, solar cells and nanowire lasers. We present a direct method developed to calcula…
