铁电体中的统计开关动力学
Statistical switching kinetics in ferroelectrics
摘要：
通过假设一个更现实的成核和极化反转的情况下，我们建立了一个新的统计开关模型的铁电体，这是不同的Kolmogorov-Avrami-Ishibashi（KAI）模型或成核有限开关（NLS）模型。该模型在引入了随时间变化的退偏场后，较好地描述了多晶薄膜在中、低场下的延迟行为，这是传统KAI模型所不能描述的。该模型正确地预测了n=1的多晶薄膜在高Eappl或陶瓷块在理想情况下。
英文摘要：
By assuming a more realistic nucleation and polarization reversal scenario we build a new statistical switching model for ferroelectrics, which is different from either the Kolmogorov-Avrami-Ishibashi (KAI) model or the Nucleation-Limited-Switching (NLS) model. After incorporating a time-dependent depolarization field this model gives a good description about the retardation behavior in polycrystalline thin films at medium or low fields, which can not be described by the traditional KAI model. This model predicts correctly n=1 for polycrystalline thin films at high Eappl or ceramic bulks in the ideal case.
