Magnetic field dependent transmission phase of a double dot system in a quantum ring
M. Sigrist, A. Fuhrer, T. Ihn +4
The Aharonov-Bohm effect is measured in a four-terminal open ring geometry based on a Ga[Al]As heterostructure. Two quantum dots are embedded in the structure, one in each of the t…

Transmission Phase Through Two Quantum Dots Embedded in a Four-Terminal Quantum Ring
M. Sigrist, A. Fuhrer, T. Ihn +3
We use the Aharonov-Bohm effect in a four-terminal ring based on a Ga[Al]As heterostructure for the measurement of the relative transmission phase. In each of the two interfering p…
