High-frequency gate manipulation of a bilayer graphene quantum dot
S. Dröscher, J. Güttinger, T. Mathis +3
We report transport data obtained for a double-gated bilayer graphene quantum dot. In Coulomb blockade measurements, the gate dielectric Cytop(TM) is found to provide remarkable el…
Coulomb Gap in Graphene Nanoribbons
S. Dröscher, H. Knowles, Y. Meir +2
We investigate the density and temperature-dependent conductance of graphene nanoribbons with varying aspect ratio. Transport is dominated by a chain of quantum dots forming sponta…
Coherent Electron-Phonon Coupling in Tailored Quantum Systems
P. Roulleau, S. Baer, T. Choi +6
The coupling between a two-level system and its environment leads to decoherence. Within the context of coherent manipulation of electronic or quasiparticle states in nanostructure…
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…
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…
Quantum capacitance and density of states of graphene
S. Dröscher, P. Roulleau, F. Molitor +4
We report on measurements of the quantum capacitance in graphene as a function of charge carrier density. A resonant LC-circuit giving high sensitivity to small capacitance changes…
