摘要：

The onset of long-range order in the size-driven ferroelectric phase transition has been discussed extensively by use of mean field theory in the literature. In order to prevent erroneous analysis of the dielectric permitivity of nanometric sized ferroelectrics, we present a pertinent description of the dielectric susceptibility of nanostructured ferroelectrics within the context of Landau-Ginzburg theory. Consequently, we also discuss the influence of size on the dielectric permittivity of thin films and relevant implications.
