对光辅助金属有机化学气相沉积(MOCVD)在双向织构Ni衬底[以CeO2/YSZ/Y2O3(YSZ为Y稳定ZrO2)作为缓冲层]和LaAlO3(100)衬底上生长的YBa2Cu3O7-x(YBCO)薄膜进行了对比研究。 在Ni衬底上生长的YBCO薄膜比在LAO衬底上生长的温度低约30℃。此外，在Ni衬底上生长的速率比在LAO衬底上高。这种现象可以用Ni衬底的导热性能优于LAO来解释。在Ni衬底和LAO衬底上生长的YBCO薄膜的临界超导电流密度Jc分别约为0.5和1.8。 分别为MA/cm2。
A comparative study of YBa2Cu3O7-x(YBCO) films grown on biaxially textured Ni substrates [using CeO2/YSZ/Y2O3(YSZ is Y stabilized ZrO2) as buffer layers] and LaAlO3(100) substrates by photo-assisted metal organic chemical vapor deposition(MOCVD) was carried out.It is found that the growing temperature of YBCO film grown on Ni substrate is lower about 30 ℃ than that on LAO substrate.Besides,the growth rate on Ni substrate is higher than that on LAO.The phenomena can be explained by the fact that the thermal conduction of Ni substrate is better than LAO.The critical superconducting current density Jc of YBCO films grown on Ni substrate and LAO substrate are about 0.5 and 1.8 MA/cm2,respectively.
