Coherent probing of excited quantum dot states in an interferometer
Martin Sigrist, Thomas Ihn, Klaus Ensslin +2
Measurements of elastic and inelastic cotunneling currents are presented on a two-terminal Aharonov--Bohm interferometer with a Coulomb blockaded quantum dot embedded in each arm.…

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…

Fano effect in a ring-dot system with tunable coupling
A. Fuhrer, P. Brusheim, T. Ihn +4
Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open rin…
