金属/SiO2/Si基Bi4Ti3O12铁电薄膜的J-V特性
Study on the J-V Characteristics of Bi4Ti3O12 Ferroelectric Thin Film with the Metal/SiO2/p-Si Structure
【摘要】 采用sol-gel方法在Pt/Ti/SiO2/Si衬底上制备了Bi4Ti3O12铁电薄膜。测试了其在直流电场下流过铁电薄膜的漏导电流J-V特性。测量结果显示正向漏电流明显小于负向漏电流。并讨论了金属–铁电薄膜所形成的整流接触特性,以及金属/SiO2/Si基Bi4Ti3O12铁电薄膜系统在不同电压范围(0~±6V)的导电机制。
【Abstract】 The Bi4Ti3O12 ferroelectric thin film was prepared on Pt/Ti/SiO2/Si substrate by sol-gel method.The J-V characteristics were measured through metal-ferroelectric film-metal(MFM) structure under direct voltage.The resuls show that positive leakage current is smaller than negative leakage current.Then the rectifying junction characteristics of metal-ferroelectric film and different conductive mechanisms in different voltage ranges(0~±6 V) are discussed.
