摘要:
A Josephson device, comprising a junction formed by forming the first layer-shaped oxide superconductor thin film including a plurality of Cu-O layers on a substrate, a barrier layer thereon and the second layer-shaped oxide superconductor thin film on the barrier layer. The Josephson device according to the present invention is manufactured by forming the first layer-shaped oxide superconductor thin film on a substrate, forming a barrier layer in the same vacuum chamber, defining patterns to said barrier layer and said first layer-shaped oxide superconductor thin film, forming an interlayer insulating film on said barrier layer, removing said interlayer insulating film in a region serving as a junction, effecting exposure to oxygen plasma, forming the second layer-shaped oxide superconductor thin film in contact with a part of the surface of said barrier layer and defining patterns to said second layer-shaped oxide superconductor thin film.
摘要:
There is disclosed a thin film superconductor in which the critical current density obtained from the magnitude of diamagnetization measured at 48 K in an outer magnetic field of 150 Oe is more than 3 mill.A/cm². Also, a manufacturing method for the thin film superconductor is disclosed in which photons having energies larger than ultraviolet rays are irradiated to the thin film superconductor on or after formation of the thin film. Further, manufacturing methods for superconductive magnetic memory, Josephson device and superconductive transistor are disclosed.
摘要:
Excellent films of a high Tc superconductor (13) are easily produced on metal coated substrates (11) at a temperature below 700°C. These metal buffer films (12) are made of Pt, Au, Ag, Pd, Ni or Ti. The film superconductivity is significantly improved by the metal buffer layer. Since it is easy to form this metal coating on a substrate, the invention can increase the potential number of usable substrates such as fibers, amorphous solids or semiconductors.
摘要:
A superconductive structure using an oxide superconductor material, featured by forming an oxide superconductor film on a semiconductor-film-coated substrate or a semiconductor substrate. It becomes possible to integrate the superconductive structure with a semiconductor device, affording varieties of practical uses and a high industrial value.
