Coexistence of Weak Localization and a Metallic Phase in Si/SiGe Quantum Wells
V. Senz, T. Heinzel, T. Ihn +4
Magnetoresistivity measurements on p-type Si/SiGe quantum wells reveal the coexistence of a metallic behavior and weak localization. Deep in the metallic regime, pronounced weak lo…
In-plane gate single-electron transistor in Ga[Al]As fabricated by scanning probe lithography
S. Luescher, A. Fuhrer, R. Held +3
A single-electron transistor has been realized in a Ga[Al]As heterostructure by oxidizing lines in the GaAs cap layer with an atomic force microscope. The oxide lines define the bo…
Shifting a Quantum Wire through a Disordered Crystal: Observation of Conductance Fluctuations in Real Space
T. Heinzel, G. Salis, R. Held +4
A quantum wire is spatially displaced by suitable electric fields with respect to the scatterers inside a semiconductor crystal. As a function of the wire position, the low-tempera…
Non-Gaussian distribution of nearest-neighbour Coulomb peak spacings in metallic single electron transistors
M. Furlan, T. Heinzel, B. Jeanneret +2
The distribution of nearest-neighbour spacings of Coulomb blockade oscillation peaks in normal conducting aluminum single electron transistors is found to be non-Gaussian. A pronou…
Zero-field spin splitting in InAs-AlSb quantum wells revisited
S. Brosig, K. Ensslin, R. J. Warburton +4
We present magnetotransport experiments on high-quality InAs-AlSb quantum wells that show a perfectly clean single-period Shubnikov-de Haas oscillation down to very low magnetic fi…
Paramagnetic reentrant effect in high purity mesoscopic AgNb proximity structures
F. Bernd Mueller-Allinger, Ana Celia Mota
We discuss the magnetic response of clean Ag coated Nb proximity cylinders in the temperature range 150 μK < T < 9 K. In the mesoscopic temperature regime, the normal metal-superco…
Mode Spectroscopy and Level Coupling in Ballistic Electron Waveguides
G. Salis, T. Heinzel, K. Ensslin +4
A tunable quantum point contact with modes occupied in both transverse directions is studied by magnetotransport experiments. We use conductance quantization of the one-dimensional…
