Abstract
A superconducting structure is provided. In one example, the superconducting layer includes a substrate, a patterned seed layer on the substrate and a superconducting layer on the patterned seed layer and the substrate. The superconducting layer includes a first portion with a first resistivity directly on the substrate and a second portion with a second resistivity directly on the patterned seed layer.
