Electrical Admittance of Radially and Circumferentially Polarized Barium Titanate Cylinders

Dc and Ac Electrical Properties of Ptc Barium Titanate Ceramics

The dc and ac electrical properties of PTC barium titanate ceramics were measured in the temperature range from 30 to 450°C. The Heywang's model alone is not sufficient to perform a quantitative analysis of the results. The heterogeneity of the system is taken into account.

Ferroelectric Lead Zirconate Titanate and Barium Titanate Nanotubes

Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...

Electrical bistability in a composite of polymer and barium titanate nanoparticles.

Growth in the use of organic materials in the fabrication of electronic devices is on the rise. Recently, some attempts have been undertaken to manufacture polymer memory devices. Such devices are fabricated by depositing a blend (an admixture of organic polymer, small organic molecules and nanoparticles) between two metal electrodes. These devices show two electrical conductivity states ('high...
