Visualizing Polarization Domains in Barium Titanate
The 2012 IEEE Visualization Contest’s topic was the detection of phase transitions in ferroelectric materials—in particular, barium titanate (BaTiO3). (For more on the contest, see the sidebar.) Ferroelectric materials’ electric properties make them suitable for a variety of applications. One major application is high-permittivity capacitors. Several ferroelectric materials are promising altern...
متن کاملVisualization of Polarization Domains in Barium Titanate
We present a combination of techniques from molecular, flow, and scalar data visualization to reveal the characteristics and processes in the data of this year’s IEEE scientific visualization contest. Among the challenges we had to address were the strong thermal vibration of the molecular data as well as the fact that the simulated material did not behave as we would have expected according to...
متن کاملFerroelectric 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...
متن کاملLarge Electrocaloric Effect in Relaxor Ferroelectric and Antiferroelectric Lanthanum Doped Lead Zirconate Titanate Ceramics
Both relaxor ferroelectric and antiferroelectric materials can individually demonstrate large electrocaloric effects (ECE). However, in order to further enhance the ECE it is crucial to find a material system, which can exhibit simultaneously both relaxor ferroelectric and antiferroelectric properties, or easily convert from one into another in terms of the compositional tailoring. Here we repo...
متن کاملBarium Titanate Nanoparticles in Block Copolymer
Cubic BaTiO3 particles of∼10 nm were crystallized predominantly within the hydroxylated polybutadiene matrix of a phase separated triblock copolymeric thin film of polystyrene-polybutadiene-polystyrene (Kraton D1102). The barium titanated Kraton thin film had remnants of the cylindrical morphology of a plain Kraton thin film with an interdomain spacing of ∼23 nm. The procedure of barium titanat...
