Theoretical Analyses

The motion of charged particles on a one-dimensional lattice under the influence of dc-ac electric fields is investigated. Analytic probability propagators in real space have been obtained, taking into account of the long-range intersite interactions. It is found that the effect of dynamic localization and delocalization arises mainly from the coupling of dc fields and ac fields. Various situations for the occurrence of localization and delocalization have been discussed in detail. The theoretical analyses show that such phenomena of dynamic localization and delocalization should be observable.

Multilayered ceramic capacitors (MLCCs) with BaTiO3–BaZrO3 (BTZ) dielectric layers were fabricated, and the dielectric permittivity of the BTZ layers with different thicknesses in MLCCs was measured. The dielectric permittivity of the BTZ ceramic disk was also measured under various ac electric fields. The variation in the dielectric behaviors with the thickness of BTZ layers in MLCCs was explained by the ac-field dependence of dielectric permittivity observed in the BTZ ceramic disk. The ac-field dependence of dielectric permittivity of BTZ was markedly observed below the temperature of a broad maximum in the dielectric permittivity versus temperature (є versus T) curve. It was found that the temperature of the broad maximum shifted to the low-temperature side and the peak shape became asymmetric with increasing ac field. These changes in the dielectric properties under high ac fields were explained by a model of relaxors with the concept of the formation of polar microregions (PMRs) and the freezing of fluctuating ipoles in PMRs.
