Modelling background charge rearrangements near single-electron transistors as a Poisson process

Heinz-Olaf Müller, Miha Furlan, Thomas Heinzel +1

Background charge rearrangements in metallic single-electron transistors are modelled in two-level tunnelling systems as a Poisson process with a scale parameter as only variable.…

Analysis of the temperature-dependent quantum point contact conductance in view of the metal-insulator transition in two dimensions

V. Senz, T. Heinzel, T. Ihn +5

The temperature dependence of the conductance of a quantum point contact has been measured. The conductance as a function of the Fermi energy shows temperature-independent fixed po…

Transport properties of quantum dots with hard walls

A. Fuhrer, S. Luescher, T. Heinzel +3

Quantum dots are fabricated in a Ga[Al]As-heterostructure by local oxidation with an atomic force microscope. This technique, in combination with top gate voltages, allows us to ge…

Single hole transistor in a p-Si/SiGe quantum well

U. Doetsch, U. Gennser, T. Heinzel +5

A single hole transistor is patterned in a p-Si/SiGe quantum well by applying voltages to nanostructured top gate electrodes. Gating is achieved by oxidizing the etched semiconduct…

Shot Noise by Quantum Scattering in Chaotic Cavities

S. Oberholzer, E. V. Sukhorukov, C. Strunk +4

We have experimentally studied shot noise of chaotic cavities defined by two quantum point contacts in series. The cavity noise is determined as 1/4*2e|I| in agreement with theory…

Reentrance of the induced diamagnetism in gold-niobium proximity cylinders

F. Bernd Mueller-Allinger, Ana Celia Mota

We discuss the magnetic response of gold-niobium proximity cylinders in the temperature range 100 μK<T<9 K. The temperature dependence of the susceptibility in the diamagnetic regi…

InAs-AlSb quantum wells in tilted magnetic fields

S. Brosig, K. Ensslin, A. G. Jansen +4

InAs-AlSb quantum wells are investigated by transport experiments in magnetic fields tilted with respect to the sample normal. Using the coincidence method we find for magnetic fie…

Signatures of spin pairing in a quantum dot in the Coulomb blockade regime

S. Luescher, T. Heinzel, K. Ensslin +2

Coulomb blockade resonances are measured in a GaAs quantum dot in which both shape deformations and interactions are small. The parametric evolution of the Coulomb blockade peaks s…
