✦ Synopsis
Aromatic polyamic acid alkyl ammonium salt exhibits very good transfer behavior under suitable deposition conditions. A superconducting thin film of YBapCusOx (YBCO) on
Langmuir-Blodgett film (LB) has been obtained when the substrate temperature is higher than 5OOOC. 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 polyimde LB films.
