Highly Tunable Hybrid Quantum Dots with Charge Detection
C. Rössler, B. Küng, S. Dröscher +4
In order to employ solid state quantum dots as qubits, both a high degree of control over the confinement potential as well as sensitive charge detection are essential. We demonstr…
An in-situ tunable radio-frequency quantum point contact
Thomas Müller, Bruno Küng, Paul Studerus +5
Incorporating a variable capacitance diode into a radio-frequency matching circuit allows us to in-situ tune the resonance frequency of an RF quantum point contact, increasing the…
Imaging Localized States in Graphene Nanostructures
S. Schnez, J. Güttinger, M. Huefner +3
Probing techniques with spatial resolution have the potential to lead to a better understanding of the microscopic physical processes and to novel routes for manipulating nanostruc…
Spin States in Graphene Quantum Dots
J. Guettinger, T. Frey, C. Stampfer +2
We investigate ground and excited state transport through small (d = 70 nm) graphene quantum dots. The successive spin filling of orbital states is detected by measuring the ground…
Gating of high-mobility two-dimensional electron gases in GaAs/AlGaAs heterostructures
C. Rossler, T. Feil, P. Mensch +4
We investigate high-mobility two-dimensional electron gases in AlGaAs heterostructures by employing Schottky-gate-dependent measurements of the samples' electron density and mobili…
Observation of excited states in a graphene double quantum dot
F. Molitor, H. Knowles, S. Dröscher +8
We study a graphene double quantum dot in different coupling regimes. Despite the strong capacitive coupling between the dots, the tunnel coupling is below the experimental resolut…
