Enhanced spin-orbit coupling in core/shell nanowires
Stephan Furthmeier, Florian Dirnberger, Martin Gmitra +8
The spin-orbit coupling (SOC) in semiconductors is strongly influenced by structural asymmetries, as prominently observed in bulk crystal structures that lack inversion symmetry. H…
Hybrid Quantum Dot-2D Electron Gas Devices for Coherent Optoelectronics
F. Dettwiler, P. Fallahi, D. Scholz +5
We present an inverted GaAs 2D electron gas with self-assembled InAs quantum dots in close proximity, with the goal of combining quantum transport with quantum optics experiments.…
Magnetoresistance of individual ferromagnetic GaAs/(Ga,Mn)As core-shell nanowires
Christian H. Butschkow, Elisabeth Reiger, Stefan Geißler +6
We investigate, angle dependent, the magnetoresistance (MR) of individual self-assembled ferromagnetic GaAs/(Ga,Mn)As core-shell nanowires at cryogenic temperatures. The shape of t…
Determination of the bandgap and split-off band of wurtzite GaAs
Bernt Ketterer, Martin Heiss, Marie J. Livrozet +2
GaAs nanowires with a 100% wurtzite structure are synthesized by the vapor-liquid-solid method in a molecular beam epitaxy system, using gold as a catalyst. We use resonant Raman s…
Direct correlation of crystal structure and optical properties in wurtzite/zinc-blende GaAs nanowire heterostructures
Martin Heiß, Sonia Conesa-Boj, Jun Ren +11
A novel method for the direct correlation at the nanoscale of structural and optical properties of single GaAs nanowires is reported. Nanowires consisting of 100% wurtzite and nano…
Position controlled self-catalyzed growth of GaAs nanowires by molecular beam epitaxy
Benedikt Bauer, Andreas Rudolph, Marcello Soda +4
GaAs nanowires are grown by molecular beam epitaxy using a self-catalyzed, Ga-assisted growth technique. Position control is achieved by nano-patterning a SiO2 layer with arrays of…
