Abstract The remanant polarization in ferroelectric materials appear due to some lattice hindrances which do not allow the domains and their constituting unit cells to relax back to their previous orientations at zero value of sweeping field. This tendency appears in the form of capacitance due to shaking-up of the positive and negative charge centers of the structural unit cells in every domain leading to movement of charges throughout the system. It is this kind of movement and not the permanent dipole moment of the charges in the ferroelectric sample which becomes the cause of capacitance and hence helps the system to store energy from the applied electric field over there; the stored energy in the ferroelectric sample can be stripped off with the application of some minimum reverse field called activation field for polarization reversal. Landauer modeled average polarization current over the switching time and related rate of polarization switching with some minimum applied field below which polarization switching shall be too slow to attain saturation stage of polarization during the life time of the experiment designed for the purpose and accordingly the sample, in spite of being ferroelectric, shall not translate to ferroelectric hysteresis loop. In this paper ferroelectric switching analysis of equal wt% NaNO2-PVA composite fabricated at elevated temperature is carried.

NaNO2-PVA 复合薄膜中极化反转和极化饱和的开关相关激活场

摘要 铁电材料中的剩余极化是由于一些晶格阻碍而出现的，这些晶格阻碍不允许域及其构成的晶胞在扫描场为零值时松弛回其先前的取向。这种趋势以电容的形式出现，这是由于每个域中结构单元的正负电荷中心的抖动导致电荷在整个系统中移动。正是这种运动而不是铁电样品中电荷的永久偶极矩成为电容的原因，从而帮助系统存储来自施加在那里的电场的能量；铁电样品中储存的能量可以通过应用一些称为极化反转的激活场的最小反向场来剥离。Landauer 模拟了在切换时间和相关极化切换速率下的平均极化电流，其中一些最小外加场低于该最小外加场，在为此目的而设计的实验和相应的样品的寿命期间，极化切换将太慢而无法达到极化的饱和阶段，尽管是铁电体，但不应转化为铁电体磁滞回线。在本文中，进行了在高温下制造的等重量百分比 NaNO2-PVA 复合材料的铁电开关分析。
