Paper Abstract

Bi2Sr2Ca1Cu2O7-x(BSCCO) superconducting films were deposited on Si substrates with buffer layers of Y- stabilized ZrO2 films (YSZ) by magnetic sputtering. The critical temperature (Tc) of BSCCO film on YSZ/Si was 82 K. The microstructure of BSCCO/YSZ/Si was studied by scanning electronic microscope (SEM) and atom force microscope (AFM), the growing model of spiral nucleation was verified. Fractal images were found in the micrographs, and their growth mechanism was presented.
