Abstract
The modified Landau-type free-energy expression and the Landau–Khalatnikov equation of motion are first used to study the influence of electrodes on the properties of polarization reversal in a ferroelectric thin film with surface transition layers. The combined influence of the electrodes and surface transition layers on the dynamic properties, including polarization-reversal distribution, hysteresis loops, and switching current of the ferroelectric thin films, is discussed in detail. The results show that the electrode materials can greatly affect the dynamic properties of a ferroelectric thin film.
