摘要
The semiconductor-superconductor con tact system of Ge/Y-Ba-Cu-O(YBCO)/SrTiO_(3) has been successfully fabricated by two steps of deposition.The YBCO film in the contact of Ge/YBCO did not lose its superconductivity and its T_(c)(on set)did not degrade as well.The top layer of Ge was polycrystalline with preferred orientation corresponding to the epitaxial structure of the underlayer of YBCO.
