Spin-orbit coupling and anisotropy of spin splitting in quantum dots
J. Konemann, R. J. Haug, D. K. Maude +2
In lateral quantum dots, the combined effect of both Dresselhaus and Bychkov-Rashba spin orbit coupling is equivalent to an effective magnetic field B_so which has the opposite sig…
Impurity effects in quantum dots: Towards quantitative modeling
E. Rasanen, J. Konemann, R. J. Haug +2
We have studied the single-electron transport spectrum of a quantum dot in GaAs/AlGaAs resonant tunneling device. The measured spectrum has irregularities indicating a broken circu…
Correlation-function spectroscopy of inelastic lifetime in heavily doped GaAs heterostructures
J. Könemann, P. König, T. Schmidt +3
Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential…
Magneto-optical evidence of the percolation nature of the metal-insulator transition in the 2D electron system
I. V. Kukushkin, Vladimir I. Fal'ko, R. J. Haug +2
We compare the results of the transport and time-resolved magneto-luminescence measurements in disordered 2D electron systems in GaAs-AlGaAs heterostructures in the extreme quantum…
Spectroscopy of Local Density of States Fluctuations in a Disordered Conductor (Experiment)
T. Schmidt, R. J. Haug, V. I. Fal'ko +3
The local density of states of a degenerate semiconductor is investigated at low magnetic fields. In order to realize this experiment, we designed a strongly asymmetric double-barr…
