Large nuclear spin polarization in gate-defined quantum dots using a single-domain nanomagnet
Gunnar Petersen, Eric A. Hoffmann, Dieter Schuh +3
The electron-nuclei (hyperfine) interaction is central to spin qubits in solid state systems. It can be a severe decoherence source but also allows dynamic access to the nuclear sp…
Counting Statistics and Dephasing Transition in an Electronic Mach-Zehnder Interferometer
A. Helzel, L. V. Litvin, I. P. Levkivskyi +3
It was recently suggested that a novel type of phase transition may occur in the visibility of electronic Mach-Zehnder Interferometers. Here, we present experimental evidence for t…
Cyclic Depopulation of Edge States in a large Quantum Dot
Stephan Baer, Clemens Rössler, Thomas Ihn +3
We investigate magneto-transport through a 1.6 μm wide quantum dot (QD) with adjacent charge detector, for different integer filling factors in the QD and constrictions. When this…
Effect of rotation of the polarization of linearly polarized microwaves on the radiation-induced magnetoresistance oscillations
A. N. Ramanayaka, R. G. Mani, J. Iñarrea +1
Light-matter coupling is investigated by rotating, by an angle θ, the polarization of linearly polarized microwaves with respect to the long-axis of GaAs/AlGaAs Hall-bar electron d…
Tunable Charge Detectors for Semiconductor Quantum Circuits
Clemens Rössler, Tobias Krähenmann, Stephan Baer +4
Nanostructures defined in high-mobility two-dimensional electron systems offer a unique way of controlling the microscopic details of the investigated device. Quantum point contact…
Interference of electrons in backscattering through a quantum point contact
A. A. Kozikov, C. Rössler, T. Ihn +3
Scanning gate microscopy is used to locally investigate electron transport in a high-mobility two-dimensional electron gas formed in a GaAs/AlGaAs heterostructure. Using quantum po…
Enlarged magnetic focusing radius of photoinduced ballistic currents
Markus Stallhofer, Christoph Kastl, Marcel Brändlein +5
We exploit GaAs-based quantum point contacts as mesoscopic detectors to analyze the ballistic flow of photogenerated electrons in a two-dimensional electron gas at a perpendicular…
