研究了PZT 30/70种子层作为成核助剂对0.93PMN-0.07PT薄膜微结构和电学性能的影响。烧绿石相在650°C的退火温度下完全消失。结果表明,晶种0.93PMN-0.07PT薄膜结构致密,晶粒尺寸较大,介电常数、自发极化强度和高温系数均高于未晶种薄膜。两种膜中的细P-E环和频率依赖性T_(mobserved)表明了类似弛豫的行为。
This paper investigated the effect of PZT30/70 seed layer as a nucleation aid on the microstructure and electrical properties of 0.93PMN-0.07PT thin films. Pyrochlore phase was totally eliminated at an annealing temperature as low as 650°C. Seeded 0.93PMN-0.07PT thin film possessed a denser structure, larger grain size, and thus higher permittivity, spontaneous polarization and pyrocoefficient than unseeded film. The slim P-E loops and the frequency dependentTmobserved in both films indicated a relaxor-like behavior.
