摘要: The imprint effect in ferroelectrics often hinders their performance practical applications. Large numbers of observations have been reported on the inorganic ferroelectrics, while ferroelectric polymers has attracted attention just recent years. Here we our studies poly(vinylidene fluoride-trifluoroethylene) thin films. We measured shift switching peaks and increase time as a function waiting time. influences pulse profile short-circuit condition were also determined. According to interface screening model, discussed origin explained experimental observations.
