Electron counting in quantum dots
S. Gustavsson, R. Leturcq, M. Studer +5
We use time-resolved charge detection techniques to investigate single-electron tunneling in semiconductor quantum dots. The ability to detect individual charges in real-time makes…
Universality of Bias- and Temperature-induced Dephasing in Ballistic Electronic Interferometers
Y. Yamauchi, M. Hashisaka, S. Nakamura +8
We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-Perot type interferometer. In both cases we found that the interference signal is reversed at a c…
Gate-controlled spin-orbit interaction in a parabolic GaAs/AlGaAs quantum well
M. Studer, G. Salis, K. Ensslin +2
We study the tunability of the spin-orbit interaction in a two-dimensional electron gas with a front and a back gate electrode by monitoring the spin precession frequency of drifti…
Statistical electron excitation in a double quantum dot induced by two independent quantum point contacts
U. Gasser, S. Gustavsson, B. Küng +4
We investigate experimentally the influence of current flow through two independent quantum point contacts to a nearby double quantum dot realized in a GaAs-AlGaAs heterostructure.…
Detecting single-electron tunneling involving virtual processes in real time
S. Gustavsson, M. Studer, R. Leturcq +4
We use time-resolved charge detection techniques to probe virtual tunneling processes in a double quantum dot. The process involves an energetically forbidden state separated by an…
Frequency-selective single photon detection using a double quantum dot
S. Gustavsson, M. Studer, R. Leturcq +4
We use a double quantum dot as a frequency-tunable on-chip microwave detector to investigate the radiation from electron shot-noise in a near-by quantum point contact. The device i…
