Anisotropic electronic transport and Rashba effect of the two-dimensional electron system in (110) SrTiO-based heterostructures
K. Wolff, R. Eder, R. Schäfer +2
The two-dimensional electron system in (110)AlO/SrTiO heterostructures displays anisotropic electronic transport. Largest and lowest conductivity and electron mobil…
Anisotropic electronic transport of the two-dimensional electron system in Al2O3/SrTiO3 heterostructures
K. Wolff, R. Schäfer, M. Meffert +3
Transport measurements on the two dimensional electron system in Al2O3 SrTiO3 heterostructures indicate significant noncrystalline anisotropic behavior below T = 30 K. Lattice disl…
Unusual resistance-voltage dependence of nanojunctions during electromigration in ultra-high vacuum
D. Stöffler, M. Marz, B. Kießig +4
The electrical resistance R of metallic nanocontacts subjected to controlled cyclic electromigration in ultra-high vacuum has been investigated in-situ as a function of applied vol…
One-dimensional Josephson junction arrays: Lifting the Coulomb blockade by depinning
Nicolas Vogt, Roland Schäfer, Hannes Rotzinger +4
Experiments with one-dimensional arrays of Josephson junctions in the regime of dominating charging energy show that the Coulomb blockade is lifted at the threshold voltage, which…
Dependence of the Macroscopic Quantum Tunneling Rate on Josephson Junction Area
Christoph Kaiser, Roland Schäfer, Michael Siegel
We have carried out systematic Macroscopic Quantum Tunneling (MQT) experiments on Nb/Al-AlO_x/Nb Josephson junctions (JJs) of different areas. Employing on-chip lumped element indu…
