摘要：
Aromatic polyamic acid alkyl ammonium salt exhibits very good transfer behavior under suitable deposition conditions. A superconducting thin film of YBa2Cu3Ox (YBCO) on Langmuir-Blodgett film (LB) has been obtained when the substrate temperature is higher than 500°C. Superconducting edge junctions of (Pb-In)/LB/(Pb-In) and YBCO/LB/YBCO incorporated with polyimide LB films were fabricated. Their current-voltage characteristics are discussed in terms of the temperature stability of polyimide LB films.
