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…

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…

Transport through graphene double dots

F. Molitor, S. Dröscher, J. Güttinger +4

We present Coulomb blockade measurements in a graphene double dot system. The coupling of the dots to the leads and between the dots can be tuned by graphene in-plane gates. The co…

Energy gaps in etched graphene nanoribbons

C. Stampfer, J. Guettinger, S. Hellmueller +3

Transport measurements on an etched graphene nanoribbon are presented. It is shown that two distinct voltage scales can be experimentally extracted that characterize the parameter…

Transport gap in side-gated graphene constrictions

F. Molitor, A. Jacobsen, C. Stampfer +3

We present measurements on side gated graphene constrictions of different geometries. We characterize the transport gap by its width in back gate voltage and compare this to an ana…
