Abstract

In edge-junction technology, variations of the Josephson current density j(m) across chip and wafer are substantially larger than those observed in planar technology. The current density depends strongly on the orientation of the edge on the wafer. This problem can be significantly reduced when using non-linear, particularly funnel-shaped edge-junctions rather than linear junctions.
