| Abstract: | To explain the fast motion of ferroelectric-paraelectric interface, a mechanism based on latent heat release and conduction has been introduced. Its finite-size effect shows that the velocity of interface motion increases with decreasing system thickness. The theoretical results agree with experiments. |
