Abstract
The switching process of ferroelectric P(VDF-TrFE) thin films with different thicknesses is investigated through transient switching current measurements. The profile of the transient current shows a strong size effect, i.e. whether there is a peak in the transient current depends on film thickness. The different switching current profiles are attributed to a transition of switching kinetics, characterized by a unique field dependent switching time turning to a distribution of switching times in the system. Furthermore, transient current at different temperature is evaluated. The Arrhenius dependence of peak time indicates that the switching process is thermally activated.
