Exciton Footprint of Self-assembled AlGaAs Quantum Dots in Core-Shell Nanowires
Yannik Fontana, Pierre Corfdir, Barbara Van Hattem +7
Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilit…
Quantum dot opto-mechanics in a fully self-assembled nanowire
M. Montinaro, G. Wüst, M. Munsch +6
We show that fully self-assembled optically-active quantum dots (QDs) embedded in MBE-grown GaAs/AlGaAs core-shell nanowires (NWs) are coupled to the NW mechanical motion. Oscillat…
Electrical transport in C-doped GaAs nanowires: surface effects
Alberto Casadei, Jil Schwender, Eleonora Russo-Averchi +7
The resistivity and the mobility of Carbon doped GaAs nanowires have been studied for different doping concentrations. Surface effects have been evaluated by comparing upassivated…
Single nanowire solar cells beyond the Shockley-Queisser limit
Peter Krogstrup, Henrik Ingerslev Jørgensen, Martin Heiss +5
Light management is of great importance to photovoltaic cells, as it determines the fraction of incident light entering the device. An optimal pn-junction combined with an optimal…
Doping incorporation paths in catalyst-free Be-doped GaAs nanowires
Alberto Casadei, Peter Krogstrup, Martin Heiss +7
The incorporation paths of Be in GaAs nanowires grown by the Ga-assisted method in molecular beam epitaxy has been investigated by electrical measurements of nanowires with differe…
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…
