Phase Transition Properties of Ferroelectric Polymer Films

Piezoelectric and pyroelectric properties of ferroelectric Langmuir-Blodgett polymer films

Dielectric Properties and Morphology of Ferroelectric Ceramic-Polymer Composite Films

Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was examined using laser scanning confocal microscopy, which is capable to measure small particle distributions in more details than conventional microscopy. The thin-slice images allowed us to visualize the micronsize particles and the polymer...

Dielectric properties of ferroelectric thin films with surface transition layers.

By taking into account surface transition layers (STL), the dielectric properties of ferroelectric thin films described by the transverse Ising model are discussed in the framework of the mean field approximation. Functions of the intra-layer and inter-layer couplings are introduced to characterize STL, which makes the model more realistic compared to previous treatment of surface layers using ...

Electrocaloric Effect (ECE) in Ferroelectric Polymer Films

The electrocaloric effect (ECE) is the change in temperature and/or entropy of a dielectric material due to the electric field induced change of dipolar states. Electrocaloric effect in dielectrics is directly related to the polarization changes under electric field.[1-3,6] Hence a large polarization change is highly desirable in order to achieve a large ECE which renders the ferroelectric mate...
