摘要
采用磁控溅射技术在Si基底上制备了(Pb1-xSrx)TiO3(简称PST)铁电薄膜,采用双极性、双脉冲方波电压测试了其极化反转特性。测试结果表明,所制备的PST铁电薄膜的电流密度峰值达10-4A/mm2量级,开关时间可达1.0 ms左右,极化反转特性较好,有望未来在Si基集成单片红外探测焦平面阵列研制中加以应用。
The Si-based (Pb1-xSrx)TiO3 ferroelectric thin films were prepared successf magnetron sputtering in this paper. The polarization reversal characteristics of (Pb1-xSrx) ferroelectric thin films were measured by square-wave voltage with double polarity and dou ly by TiO3 e impulse. The density peak of polarization reversal current was 10^-4A/mmz order and polarization reversal time was 1.0 ms or so. The preparation of Si-based ferroelectric thin films with excellent properties is beneficial to the fabrication of Si-based single chip IR focal plane array device.
