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...
متن کاملMultiferroic Phases and Transitions in Ferroelectric Lead Titanate Nanodots
Discovery of novel phases and their associated transitions in low-dimensional nanoscale systems is of central interest as the origin of emergent phenomena and new device paradigms. Although typical ferroelectrics such as PbTiO3 exhibit diverse phase transition sequences, the conventional incompatible mechanisms of ferroelectricity and magnetism keep them as simply nonmagnetic phases, despite th...
متن کاملUltrahigh density array of epitaxial ferroelectric nanoislands on conducting substrates.
An ultrahigh density array of epitaxial PbTiO(3) (PTO) nanoislands with uniform size was fabricated on a single-crystalline Nb-doped SrTiO(3) (100) substrate over a large area (cm(2) scale) by simple but robust method utilizing polystyrene-block-poly(4-vinylpridine) copolymer micelles. Each nanoisland has an average volume of 2.6 x 10(3) nm(3) (a height of 7 nm and a diameter of 22 nm). Because...
متن کاملEffects of residual (or internal) stress on ferroelectric domain wall motion in tetragonal lead titanate
The effect of temperature on grinding-induced texture in tetragonal lead titanate (PT) has been investigated as a function of the magnitude of loading applied to the sample surface during grinding, using in situ x-ray diffraction (XRD) with an area detector. Compared to the ground PT under lower loading conditions (5 N), the ground PT under higher loading conditions (40 N) retains strong ferroe...
متن کاملFerroelectric triggering of carbon monoxide adsorption on lead zirco-titanate (001) surfaces
Atomically clean lead zirco-titanate PbZr0.2Ti0.8O3 (001) layers exhibit a polarization oriented inwards P(-), visible by a band bending of all core levels towards lower binding energies, whereas as introduced layers exhibit P(+) polarization under air or in ultrahigh vacuum. The magnitude of the inwards polarization decreases when the temperature is increased at 700 K. CO adsorption on P(-) po...
