Low-temperature formation of multilayered Bi(Pb)-Sr-Ca-Cu-O thin films by successive deposition using laser ablation

Crystallized as-grown Bi(Pb)-Sr-Ca-Cu-O thin films are formed by the laser ablation method at a substrate temperature as low as 480 °C under N₂O gas flow. Moreover, the as-grown thin film, which has a crystal structure consisting of four or five CuO₂ layers between adjacent Bi₂O₂ layers, can be formed by the combination of N₂O gas flow and the successive deposition method with excimer laser pulses.
