Kondo effect in a few-electron quantum ring
U. F. Keyser, C. Fuhner, S. Borck +4
A small quantum ring with less than 10 electrons was studied by transport spectroscopy. For strong coupling to the leads a Kondo effect is observed and used to characterize the spi…

Aharonov-Bohm oscillations of a tunable quantum ring
U. F. Keyser, S. Borck, R. J. Haug +3
With an atomic force microscope a ring geometry with self-aligned in-plane gates was directly written into a GaAs/AlGaAs-heterostructure. Transport measurements in the open regime…
