Transport signatures of correlated disorder in a two-dimensional electron gas
T. Heinzel, R. D. Jaeggi, E. Ribeiro +5
We report electronic transport measurements on two-dimensional electron gases in a Ga[Al]As heterostructure with an embedded layer of InAs self-assembled quantum dots. At high InAs…
Energy spectra of quantum rings
A. Fuhrer, S. Luescher, T. Ihn +4
Ring geometries have fascinated experimental and theoretical physicists over many years. Open rings connected to leads allow the observation of the Aharonov-Bohm effect, a paradigm…
Analysis of the resistance in p-SiGe over a wide temperature range
V. Senz, T. Ihn, T. Heinzel +6
The temperature dependence of a system exhibiting a `metal-insulator transition in two dimensions at zero magnetic field' (MIT) is studied up to 90K. Using a classical scattering m…
The Hanbury Brown and Twiss Experiment with Fermions
S. Oberholzer, M. Henny, C. Strunk +4
We realized an equivalent Hanbury Brown and Twiss experiment for a beam of electrons in a two dimensional electron gas in the quantum Hall regime. A metallic split gate serves as a…
