Preparation of Bi2Sr2Can−1 CunO2n+4 (n=1, 2, 3 and 4) thin films by MOCVD

Abstract We have fabricated Bi 2 Sr 2 Ca n−1 Cu n O 2n+4 superconducting thin films by metalorganic chemical vapor deposition (MOCVD) using triphenyl bismuth and β-diketonates of Sr, Ca and Cu as source materials. Films were obtained by changing the source vessel temperatures. The films for n=3 showed the highest zero resistance temperature of 86K among the films of the Bi 2 Sr 2 Ca n−1 Cu n O 2n+4 (n=1, 2, 3 and 4).
