We study the dynamics of polarization switching in a superlattice consisting of periodic ferroelectric and paraelectric layers. The dynamics of switching is examined based on the Landau‐Khalatnikov equation of motion. Effect of interface coupling on the transient behaviors of polarization and switching time are examined in detail. The spatial distribution of polarizations at different times in switching is illustrated. Our results reveal that the interface coupling plays an important role in determining the switching dynamics of the superlattices. The minimum field requires for polarization switching decreases with increasing interface coupling strength, and this implies that polarization switching is interface‐aided.
