Claim:
1. A component comprising a Josephson junction, comprising: a substrate comprising at least one step edge on a textured surface thereof and a functional layer made of a high-temperature superconducting material disposed on the textured surface of the substrate such that the functional layer also comprises at least one step edge, wherein a grain boundary that forms a weak link of the Josephson junction is present at the at least one step edge of the functional layer, wherein texturedness of the textured surface of the substrate and/or at least one first textured buffer layer disposed between the substrate and the functional layer causes, on both sides of the at least one step edge of the functional layer, an a crystal axis or a b crystal axis or both crystal axes in a plane of the functional layer to be oriented perpendicularly to the grain boundary to within a deviation of no more than 10° wherein the textured surface of the substrate and/or the at least one first textured buffer layer comprises elevations and/or depressions having an average height or depth of between 1 nm and 10 nm.
