掺杂对铁酸铋薄膜漏电流及铁电性的影响OA北大核心CSCDCSTPCD
Effects of Doping on Leakage Current and Ferroelectricity of Bismuth Ferrite Films
铁酸铋是目前最为重要的室温单相多铁性材料,其禁带宽度较小,具有较大的剩余极化强度与较高的铁电居里温度,在铁电随机存储器、光电器件等领域有着极佳的应用前景.但铁酸铋薄膜因Bi3+挥发和Fe3+的部分还原,易产生较大漏电流而制约了其实际应用.对铁酸铋薄膜进行掺杂,是改善其电性能的一种有效手段.围绕如何通过铁酸铋薄膜A位和B位掺杂来减少Bi3+挥发和抑制Fe3+还原,从引入掺杂离子后发生的缺陷反应和微结构变化等方面,对国内外近年来关于铁酸铋薄膜电性能掺…查看全部>>
Bismuth ferrite is the most important single-phase multiferroic material at room temperature. Because of its small band gap, high remnant polarization and curie temperature, bismuth ferrite is widely used in such fields as ferroelectric random access memory and optoelectronic devices. However, strong leakage current will be produced in bismuth ferrite films due to vo-latilization of Bi3+and partial reduction of Fe3+in preparation process, which restricts its…查看全部>>
