Bi_4Ti_3O_~12 (BTO) was prepared on LSCO and Pt substrates respectively. It was found that LSCO could affect crystallization of BTO,the breakdown and ferroelectric properties of BTO prepared on LSCO were better than those of BTO prepared on Pt.

• 分别在LSCO和Pt衬底上制备了Bi_4Ti_3O_(12)(BTO)薄膜,分析结果表明,使用LSCO衬底对BTO的析晶有影响,击穿电压、铁电特性均有较大改善。
