Spatial mapping and manipulation of two tunnel-coupled quantum dots
Magdalena Huefner, Bruno Kueng, Stephan Schnez +4
The metallic tip of a scanning force microscope operated at 300 mK is used to locally induce a potential in a fully controllable double quantum dot defined via local anodic oxidati…
Raman spectroscopy on etched graphene nanoribbons
Dominik Bischoff, Johannes Güttinger, Susanne Dröscher +3
We investigate etched single-layer graphene nanoribbons with different widths ranging from 30 to 130 nm by confocal Raman spectroscopy. We show that the D-line intensity only depen…
Time-resolved charge detection in graphene quantum dots
J. Guettinger, J. Seif, C. Stampfer +3
We present real-time detection measurements of electron tunneling in a graphene quantum dot. By counting single electron charging events on the dot, the tunneling process in a grap…
Transport through a strongly coupled graphene quantum dot in perpendicular magnetic field
J. Guettinger, C. Stampfer, T. Frey +2
We present transport measurements on a strongly coupled graphene quantum dot in a perpendicular magnetic field. The device consists of an etched single-layer graphene flake with tw…
Characterization of a microwave frequency resonator via a nearby quantum dot
T. Frey, P. J. Leek, M. Beck +3
We present measurements of a hybrid system consisting of a microwave transmission-line resonator and a lateral quantum dot defined on a GaAs heterostructure. The two subsystems are…
