Sub-μm Josephson Junctions for Superconducting Quantum Devices
J. M. Meckbach, M. Merker, S. J. Buehler +7
For high-performance superconducting quantum devices based on Josephson junctions (JJs) decreasing lateral sizes is of great importance. Fabrication of sub-μm JJs is challenging du…
Direct current superconducting quantum interferometers with asymmetric shunt resistors
M. Rudolph, J. Nagel, J. M. Meckbach +5
We have investigated asymmetrically shunted Nb/Al-AlO/Nb direct current (dc) superconducting quantum interference devices (SQUIDs). While keeping the total resistance ident…
Geometry-induced reduction of the critical current in superconducting nanowires
D. Henrich, P. Reichensperger, M. Hofherr +5
Reduction of the critical current in narrow superconducting NbN lines with sharp and rounded bends with respect to the critical current in straight lines was studied at different t…
Spectroscopy of a fractional Josephson vortex molecule
U. Kienzle, J. M. Meckbach, K. Buckenmaier +8
In long Josephson junctions with multiple discontinuities of the Josephson phase, fractional vortex molecules are spontaneously formed. At each discontinuity point a fractional Jos…
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…
