Abstract

Bi-Sr-Ca-Cu-0 thin films were prepared on (110)SrTiO3 by coevaporation with rf oxygen plasma. The non-(00n) crystalline orientations were formed in the Bi2 Sr2Ca2Cu3Oy1 Bi2Sr2 CaCu2Oy2 and Bi2Sr2CuOy3 phases. Furthermore, it was confirmed that the chemical composition and the oxygen plasma condition influenced the crystalline orientation. On the basis of these results, a new idea for the film growth mechanism is proposed.
