Abstract
A mesa-shaped superconducting-superlattice structure is formed and adhered with epoxy onto a dielectric substrate where plural superconducting layers and plural insulating layers are naturally and alternately stacked. A λ/4 micro strip line (which means the length of the strip line is one-fourth of the wavelength of a microwave to be introduced) is electrically connected via a metallic film onto the mesa structural portion of the superconducting-superlattice structure, and a metallic electrode is electrically connected to the additional mesa structural portion of the superconducting-superlattice structure via a metallic film.
Claims5
A device for generating a constant voltage comprising:
- a dielectric substrate,
- a mesa-shaped superconducting-superlattice structure where plural superconducting layers and plural insulating layers are naturally and alternately stacked and which is formed on said dielectric substrate,
- a micro strip line for introducing a microwave which is formed so as to be electrically contacted to a top surface of a mesa structural portion of said superconducting-superlattice structure, and
- a metallic electrode for outputting voltages induced by said microwave so as to be electrically connected to at least one portion of said superconducting-superlattice structure.
- wherein said mesa structural portion of said superconducting-superlattice structure is covered with an insulating layer and at least one side end of said superconducting-superlattice structure is covered with an insulating member, and a top surface of said mesa structural portion, a top surface of said insulating layer and a top surface of said insulating member are covered with at least one of said micro strip line and said metallic electrode.
