Abstract We investigated switching behavior in PVA based NaNO2-CsNO3 mixed system composite films fabricated at moderate elevated temperature. The switching transients in ‘ceramic-polymer mixed system’ exhibiting best ferroelectric response optimized with CsNO3 mole% 0.09 have been analyzed by two different approaches. Following Landauer approach, an activation field is calculated by measuring the rate at which ‘polarization switching’ takes place; it is calculated by measuring average polarization current under the switching transient over the switching time. In second approach, another kind of activation field is calculated by measuring maximum value of polarization current attained in the transient. The calculation of the activation field in the former approach gives the value of minimum field required to take the sample into its saturated state of polarization during the life time of the experiment whereas the one calculated from later approach helps to find the activation field which is just sufficient to initiate the state of polarization reversal.

在中等高温下制备的基于 PVA 的 NaNO2-CsNO3 混合体系复合薄膜中用于极化反转和极化饱和的开关相关激活场

摘要 我们研究了在中等高温下制备的 PVA 基 NaNO2-CsNO3 混合体系复合薄膜的开关行为。已经通过两种不同的方法分析了“陶瓷-聚合物混合系统”中的开关瞬变，该系统表现出最佳铁电响应，使用 CsNO3 摩尔% 0.09 进行了优化。遵循 Landauer 方法，通过测量“极化转换”发生的速率来计算激活场；它是通过在开关时间内测量开关瞬态下的平均极化电流来计算的。在第二种方法中，另一种激活场是通过测量瞬态中获得的极化电流的最大值来计算的。
