Site-selective ion beam synthesis and optical properties of individual CdSe nanocrystal quantum dots in a SiO2 matrix
H. Moritz Mangold, Helmut Karl, Hubert J. Krenner
Cadmium selenide nanocrystal quantum dots (NC-QDs) are site-selectively synthesized by sequential ion beam implantation of selenium and cadmium ions in a SiO2 matrix through sub-mi…
THz-circuits driven by photo-thermoelectric graphene-junctions
Andreas Brenneis, Felix Schade, Simon Drieschner +4
For future on-chip communication schemes, it is essential to integrate nanoscale materials with an ultrafast optoelectronic functionality into high-frequency circuits. The atomical…
Structured Back Gates for High-Mobility Two-Dimensional Electron Systems Using Oxygen Ion Implantation
Matthias Berl, Lars Tiemann, Werner Dietsche +2
We present a new approach of back gate patterning that is compatible with the requirements of highest mobility molecular beam epitaxy. Contrary to common back gating techniques, ou…
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…
Ultrafast electronic read-out of diamond NV centers coupled to graphene
Andreas Brenneis, Louis Gaudreau, Max Seifert +6
Nonradiative transfer processes are often regarded as loss channels for an optical emitter1, since they are inherently difficult to be experimentally accessed. Recently, it has bee…
