摘要：
The role of a change in the spontaneous polarization charge in the formation of negative differential conductance regions of the current-voltage characteristics of thin ferroelectric films has been determined. It has been shown that the polarization recovery current, which appears due to partial depolarization of a preliminarily polarized film, prevails over the intrinsic leakage current of the ferroelectric film in the coercive field region and corresponds to the Weibull distribution. The influence of polarization recovery current decreases with decreasing voltage sweep rate.
