Patterning of two-dimensional electron systems in SrTiO3 based heterostructures using a CeO2 template
D. Fuchs, K. Wolff, R. Schäfer +3
Two-dimensional electron systems found at the interface of SrTiO3-based oxide heterostructures often display anisotropic electric transport whose origin is currently under debate.…
Dissipation mechanism above the current threshold in Josephson junction chains
Roland Schäfer, Wanyin Cui, Kai Grube +2
We present measurements on one-dimensional Josephson junction arrays formed by a chain of SQUID loops in the regime where . We observe a blockaded zero current b…
Thermally activated conductance in arrays of small Josephson junctions
J. Zimmer, N. Vogt, A. Fiebig +7
We present measurements of the temperature-dependent conductance for series arrays of small-capacitance SQUIDs. At low bias voltages, the arrays exhibit a strong Coulomb blockade,…
Josephson vortex coupled to a flux qubit
Kirill G. Fedorov, Anastasia V. Shcherbakova, Roland Schäfer +1
Experiments towards realizing a readout of superconducting qubits by using ballistic Josephson vortices are reported. We measured the microwave radiation induced by a fluxon moving…
Aluminum Hard Mask Technique for the Fabrication of High-Quality Submicron Nb/Al-AlOx/Nb Josephson Junctions
Christoph Kaiser, J. M. Meckbach, K. Ilin +4
We have developed a combined photolithography and electron-beam lithography fabrication process for sub-\mum to \mum-size Nb/Al-AlOx/Nb Josephson junctions. In order to define the…
Conductance of the single-electron transistor: A comparison of experimental data with Monte Carlo calculations
C. Wallisser, B. Limbach, P. vom Stein +4
We report on experimental results for the conductance of metallic single-electron transistors as a function of temperature, gate voltage and dimensionless conductance. In contrast…
