Imaging the lateral shift of a quantum-point contact using scanning-gate microscopy
S. Schnez, C. Rössler, T. Ihn +3
We perform scanning-gate microscopy on a quantum-point contact. It is defined in a high-mobility two-dimensional electron gas of an AlGaAs/GaAs heterostructure, giving rise to a we…
Dipole coupling of a double quantum dot to a microwave resonator
T. Frey, P. J. Leek, M. Beck +4
Quantum coherence in solid-state systems has been demonstrated in superconducting circuits and in semiconductor quantum dots. This has paved the way to investigate solid-state syst…
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…
Irreversibility on the Level of Single-Electron Tunneling
B. Küng, C. Rössler, M. Beck +5
We present a low-temperature experimental test of the fluctuation theorem for electron transport through a double quantum dot. The rare entropy-consuming system trajectories are de…
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…
Transport Properties of Clean Quantum Point Contacts
C. Rössler, S. Baer, E. de Wiljes +5
Quantum point contacts are fundamental building blocks for mesoscopic transport experiments and play an important role in recent interference- and fractional quantum Hall experimen…
