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.
