Surface acoustic wave mediated carrier injection into individual quantum post nano emitters
Stefan Völk, Florian Knall, Florian J. R. Schülein +5
Acousto-electric charge conveyance induced by a surface acoustic wave is employed to dissociate photogenerated excitons. Over macroscopic distances, both electrons and holes are in…
Surface acoustic wave controlled carrier injection into self-assembled quantum dots and quantum posts
Hubert J. Krenner, Stefan Völk, Florian J. R. Schülein +7
We report on recent progress in the acousto-electrical control of self-assembled quantum dot and quantum post using radio frequency surface acoustic waves (SAWs). We show that the…
Direct observation of dynamic surface acoustic wave controlled carrier injection into single quantum posts using phase-resolved optical spectroscopy
S. Völk, F. Knall, F. J. R. Schülein +5
A versatile stroboscopic technique based on active phase-locking of a surface acoustic wave to picosecond laser pulses is used to monitor dynamic acoustoelectric effects. Time-inte…
Recent progress towards acoustically mediated carrier injection into individual nanostructures for single photon generation
Stefan Völk, Florian J. R. Schülein, Florian Knall +12
We report on recent progress towards single photon sources based on quantum dot and quantum post nanostructures which are manipulated using surface acoustic waves. For this concept…
Enhanced sequential carrier capture into individual quantum dots and quantum posts controlled by surface acoustic waves
Stefan Völk, Florian J. R. Schülein, Florian Knall +7
Individual self-assembled Quantum Dots and Quantum Posts are studied under the influence of a surface acoustic wave. In optical experiments we observe an acoustically induced switc…
