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…
