Excitation spectrum of two correlated electrons in a lateral quantum dot with negligible Zeeman splitting
C. Ellenberger, T. Ihn, C. Yannouleas +4
The excitation spectrum of a two-electron quantum dot is investigated by tunneling spectroscopy in conjuction with theoretical calculations. The dot made from a material with negli…
Magnetic field symmetry and phase rigidity of the nonlinear conductance in a ring
R. Leturcq, D. Sanchez, G. Gotz +4
We have performed nonlinear transport measurements as a function of a perpendicular magnetic field in a semiconductor Aharonov-Bohm ring connected to two leads. While the voltage-s…
Phase coherence in the inelastic cotunneling regime
M. Sigrist, T. Ihn, K. Ensslin +3
Two quantum dots with tunable mutual tunnel coupling have been embedded in a two-terminal Aharonov-Bohm geometry. Aharonov-Bohm oscillations are investigated in the cotunneling reg…
Cotunneling-mediated transport through excited states in the Coulomb blockade regime
R. Schleser, T. Ihn, E. Ruh +5
We present finite bias transport measurements on a few-electron quantum dot. In the Coulomb blockade regime, strong signatures of inelastic cotunneling occur which can directly be…
Finite bias charge detection in a quantum dot
R. Schleser, E. Ruh, T. Ihn +3
We present finite bias measurements on a quantum dot coupled capacitively to a quantum point contact used as a charge detector. The transconductance signal measured in the quantum…
