✦ Synopsis

Epitaxial YBa 2 Cu 3 O y (YBCO) thin films have been fabricated by chemical solution deposition (CSD) on La 2 Zr 2 O 7 -buffered YSZ single crystal substrate, where the buffer layer has three kinds of morphologyflat surface, rough surface and pore surface. The effect of LZO buffer layer's roughness on the YBCO films was evaluated by X-ray diffraction, scanning electron microscopy and temperature-dependent resistivity measurements. The flat surface of LZO layer is beneficial to highly epitaxial YBCO films and high critical current density.
