Isolating the natural edges of bilayer graphene in gate-defined mesoscopic devices
Francesco Blanda, Grazia Raciti, Thilo Glatzel +8
We introduce a graphite-gated architecture for bilayer graphene devices in which the active device is completely isolated from the natural graphene edges. Using a single patterned…
Non-equilibrium transport reveals energy level degeneracy
Artem O. Denisov, Christoph Adam, Hadrien Duprez +7
We demonstrate a method to determine energy level degeneracies using non-equilibrium electronic transport through voltage-biased quantum dots. We establish the general validity of…
Phonon spectral density in a GaAs/AlGaAs double quantum dot
Andrea Hofmann, Christian Karlewski, Andreas Heimes +6
We study phonon emission in a GaAs/AlGaAs double quantum dot by monitoring the tunneling of a single electron between the two dots. We prepare the system such that a known amount o…
Quantum dot thermometry at ultra-low temperature in a dilution refrigerator with a He immersion cell
Giorgio Nicolí, Peter Märki, Beat A. Bräm +7
Experiments performed at a temperature of a few millikelvin require effective thermalization schemes, low-pass filtering of the measurement lines and low-noise electronics. Here, w…
Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
Anisotropy and suppression of spin--orbit interaction in a GaAs double quantum dot
Andrea Hofmann, Ville F. Maisi, Tobias Krähenmann +4
The spin-flip tunneling rates are measured in GaAs-based double quantum dots by time-resolved charge detection. Such processes occur in the Pauli spin blockade regime with two elec…
Spin orbit coupling at the level of a single electron
V. F. Maisi, A. Hofmann, M. Röösli +5
We utilize electron counting techniques to distinguish a spin conserving fast tunneling process and a slower process involving spin flips in AlGaAs/GaAs-based double quantum dots.…
Transport Spectroscopy of a Spin-Coherent Dot-Cavity System
Clemens Rössler, David Oehri, Oded Zilberberg +8
Quantum engineering requires controllable artificial systems with quantum coherence exceeding the device size and operation time. This can be achieved with geometrically confined l…
