Abstract
The spontaneous polarization and electrostatic potential in ferroelectric films with domain structures have been calculated based on phenomenological theory. The polarization is reduced at the film surface due to a depolarizing field. The domain width, free energy, and Curie temperature as functions of film thickness are obtained.Keywords
