Ultrafast photodetection in the quantum wells of single AlGaAs/GaAs-based nanowires
Nadine Erhard, Stefan Zenger, Stefanie Morkötter +8
We investigate the ultrafast optoelectronic properties of single Al0.3Ga0.7As/GaAs-core-shell-nanowires. The nanowires contain GaAs-based quantum wells. For a resonant excitation o…
Photocurrents in a Single InAs Nanowire/ Silicon Heterojunction
Andreas Brenneis, Jan Overbeck, Julian Treu +7
We investigate the optoelectronic properties of single indium arsenide nanowires, which are grown vertically on p-doped silicon substrates. We apply a scanning photocurrent microsc…
Ultrafast photocurrents and THz generation in single InAs-nanowires
Nadine Erhard, Paul Seifert, Leonhard Prechtel +5
To clarify the ultrafast temporal interplay of the different photocurrent mechanisms occurring in single InAs-nanowire-based circuits, an on-chip photocurrent pump-probe spectrosco…
Dynamic Acoustic Control of Individual Optically Active Quantum Dot-like Emission Centers in Heterostructure Nanowires
Matthias Weiß, Jörg B. Kinzel, Florian J. R. Schülein +10
We probe and control the optical properties of emission centers forming in radial het- erostructure GaAs-Al0.3Ga0.7As nanowires and show that these emitters, located in Al0.3Ga0.7A…
Directional and dynamic modulation of the optical emission of an individual GaAs nanowire using surface acoustic waves
Jörg B. Kinzel, Daniel Rudolph, Max Bichler +5
We report on optical experiments performed on individual GaAs nanowires and the ma- nipulation of their temporal emission characteristics using a surface acoustic wave. We find a p…
Dissipative preparation of the exciton and biexciton in a self-assembled quantum dot on picosecond timescales
Per-Lennart Ardelt, Lukas Hanschke, Kevin A. Fischer +9
Pulsed resonant fluorescence is used to probe ultrafast phonon-assisted exciton and biexciton preparation in individual self-assembled InGaAs quantum dots. By driving the system us…
