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…
Analytic Model for the Energy Spectrum of a Graphene Quantum Dot in a Perpendicular Magnetic Field
S. Schnez, K. Ensslin, M. Sigrist +1
We analytically calculate the energy spectrum of a circular graphene quantum dot with radius R subjected to a perpendicular magnetic field B by applying the infinite-mass boundary…
Time-resolved charge detection with cross-correlation techniques
B. Küng, O. Pfäffli, S. Gustavsson +4
We present time-resolved charge sensing measurements on a GaAs double quantum dot with two proximal quantum point contact (QPC) detectors. The QPC currents are analyzed with cross-…
Charge Detection in Graphene Quantum Dots
J. Guettinger, C. Stampfer, S. Hellmueller +3
We report measurements on a graphene quantum dot with an integrated graphene charge detector. The quantum dot device consists of a graphene island (diameter approx. 200 nm) connect…
Observation of excited states in a p-type GaAs quantum dot
Y. Komijani, M. Csontos, T. Ihn +3
A quantum dot fabricated by scanning probe oxidation lithography on a p-type, C-doped GaAs/AlGaAs heterostructure is investigated by low temperature electrical conductance measurem…
