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…
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…
Optical control of internal electric fields in band-gap graded InGaN nanowires
N. Erhard, A. T. M. Golam Sarwar, F. Yang +3
InGaN nanowires are suitable building blocks for many future optoelectronic devices. We show that a linear grading of the indium content along the nanowire axis from GaN to InN int…
