Vinylidene fluoride and trifluoroethylene [P(VDF-TrFE)] ferroelectric thin film was spin-coated on Au-coated polyimide substrate and its polarization reversal was investigated by analyzing the evolution of activation field (α) with temperature. Although α is nearly a constant between 300 and 330 K, it increases linearly when temperature rates between 200 and 230 K, and between 230 and 300 K. On the other hand, the intensity of X-ray diffraction for P(VDF-TrFE) films from 200 to 330 K indicates that glass-transition process plays a significant role in both the microstructure and the polarization reversal of P(VDF-TrFE) copolymer.

Utilizing the Landau-Khalatnikov equation of motion, the polarization reversal characteristics of a ferroelectric thin film with surface transition layers have been first investigated. We have discussed the effects of the thickness, the surface transition layer parameters and the temperature on the switching properties of a ferroelectric thin film. The results show that the stronger the surface transition layer effects are, the smaller the coercive field and switching time are.
