Excitation spectra of two correlated electrons in a quantum dot
T. Ihn, C. Ellenberger, K. Ensslin +4
Measurements and a theoretical interpretation of the excitation spectrum of a two-electron quantum dot fabricated on a parabolic Ga[Al]As quantum well are reported. Experimentally,…
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.…
Time-resolved detection of single-electron interference
S. Gustavsson, R. Leturcq, M. Studer +4
We demonstrate real-time detection of self-interfering electrons in a double quantum dot embedded in an Aharonov-Bohm interferometer, with visibility approaching unity. We use a qu…
