Aharonov-Bohm effect in a side-gated graphene ring
Magdalena Huefner, Françoise Molitor, Arnhild Jacobsen +4
We investigate the magnetoresistance of a side-gated ring structure etched out of single-layer graphene. We observe Aharonov-Bohm oscillations with about 5% visibility. We are able…

Single electron charging of impurity sites visualized by scanning gate experiments on a quantum point contact
A. Pioda, S. Kicin, D. Brunner +5
A quantum point contact (QPC) patterned on a two-dimensional electron gas is investigated with a scanning gate setup operated at a temperature of 300 mK. The conductance of the poi…

Spatially resolved manipulation of single electrons in quantum dots using a scanned probe
A. Pioda, S. Kicin, T. Ihn +7
The scanning metallic tip of a scanning force microscope was coupled capacitively to electrons confined in a lithographically defined gate-tunable quantum dot at a temperature of 3…
