摘要 |
A superconductive contact or contact structure composed mainly of superconductors and a hydroxide-catalyzed bond that establishes electrical contacts, retains superconductivity, and provides the full mechanical fastening strength between the superconductors. According to the present invention, the superconductive contact structure exhibits a single-film superconductive behavior. In some embodiments, the structure has a configuration of two metallic low critical-temperature (low-T<SUB>c</SUB>) superconductors, such as niobium (Nb), connectorized by an essentially transparent and extremely thin hydroxide-catalyzed bond. In some embodiments, two ceramic high critical-temperature (high-T<SUB>c</SUB>) superconductors, such as perovskite ceramics (e.g., YBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>7 </SUB>or YBCO in general) are joined via a hydroxide-catalyzed bond. In some embodiments, a metallic low-T<SUB>c </SUB>superconductor and a ceramic high-T<SUB>c </SUB>superconductor is connectorized via a hydroxide-catalyzed bond.
