Abstract
A Josephson junction having a laminar structure which includes a substrate, a first superconductive layer deposited on the substrate, a non-superconductive layer deposited on the first superconductive layer, and a second superconductive layer deposited on the non-superconductive layer. The laminar structure has three segments, including: a first planar segment, a second planar segment, and a ramp segment connecting the two planar segments at an ascent angle thereto. The layers are of substantially uniform thickness in the three segments, with the substrate being thinner in the second planar segment than in the first planar segment and having a constantly-decreasing thickness in the ramp segment. The superconductive layers and the non-superconductive layer are deposited in-situ and are epitaxial with a c-axis in a direction substantially normal to the first and second planar segments.
