摘要：

The phenomenological Landau-Devonshire theory is used for finite size ferroelectric particles. The spatial distribution and size dependence of polarization are calculated. The latter reveals a size driven phase transition from ferroelectric to paraelectric. The ferroelectric critical size predicted is compared with that of PbTiO3 and BaTiO3 particles.
