Josephson junction semiconductor device - with reduced perturbation effect on the existing magnetic field

摘要

Device comprises a thin electric barrier (insulating) such as a semiconductor barrier layer between two sheets of superconducting metal. The substrate incorporates electrical supply leads forming a plane supporting the junction and extending perpendicular to this plane while forming a flat portion in this plane. The support has a contour limited to covering the supply leads. The second superconducting layer extends beyond the contour of the first plane to contact the leads which supply it.
