Noise thermometry in narrow 2D electron gas heat baths connected to a quasi-1D interferometer
Sven S. Buchholz, Elmar Sternemann, Olivio Chiatti +3
Thermal voltage noise measurements are performed in order to determine the electron temperature in nanopatterned channels of a GaAs/AlGaAs heterostructure at bath temperatures of 4…
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…
Probing single charge fluctuations in a semiconductor with laser spectroscopy on a quantum dot
J. Houel, A. Kuhlmann, L. Greuter +10
We probe local charge fluctuations in a semiconductor via laser spectroscopy on a nearby self-assembled quantum dot. We demonstrate that the quantum dot is sensitive to changes in…
Edge induced magneto plasmon excitation in a two-dimensional electron gas under quantum Hall conditions
Christian Notthoff, Dirk Reuter, Andreas Wieck +1
The spectrally resolved Terahertz photoconductivity between two separately contacted edge-channels of a two-dimensional electron gas in the quantum Hall regime is investigated. We…
Ultrafast mapping of optical polarization states onto spin coherence of localized electrons in a semiconductor
S. Z. Denega, M. Sladkov, D. Reuter +3
We experimentally demonstrate an ultrafast method for preparing spin states of donor-bound electrons in GaAs with single laser pulses. Each polarization state of a preparation puls…
