Formation of Bi(Pb)-Sr-Ca-Cu-O Thin Films at 500°C by a Successive Deposition Method Using Excimer Laser
Thin films of high Tc superconductors including La-Sr-Cu-O, Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O have been prepared by various methods. For a device application, as-grown superconducting films prepared with low temperature process are needed. In the present study we have prepared thin films of Bi-Sr-Ca-Cu-O (BSCCO) and Bi(Pb)-Sr-Ca-Cu-O(BPSCCO) by a laser ablation method, and have succeeded in the formation of a crystallized as-grown thin film at the substrate temperature as low as 500°C.
