Birefringence of lead titanate (PbTiO3)
Since lead titanate was ®rst grown in single-crystal form in the 1930s, several independent reports of its linear birefringence have been published. Whilst there is overall qualitative agreement on its behaviour with temperature, the absolute values show some degree of variation. At 298 K they range from ÿ0.009 to ÿ0.013, a relative spread of 40%, whilst at 673 K the discrepancy is even greater...
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 کاملNonlinear properties of lead zirconate–titanate piezoceramics
Nonlinear properties of lead zirconate-titanate ~PZT! piezoceramics are investigated using ultrasonic second harmonic generation technique. When a sinusoidal ultrasonic wave of frequency v0 is sent into a nonlinear material, the second harmonic wave with frequency 2v0 is generated. Through measuring the absolute amplitude of the fundamental (v0) and of the second harmonic (2v0) waves, the ultra...
متن کاملMicrostereolithography of lead zirconate titanate thick film on silicon substrate
Ž . Ž . The microstereolithography mSL of lead zirconate titanate PZT thick films on platinum-buffered silicon substrates is reported for Ž . the first time in this paper. Crack-free PZT thick films 80–130 mm thick have been fabricated by laser direct-write UV polymerization from the HDDA-based UV curable PZT suspensions. The characterization of the fired films shows dielectric permittivities o...
متن کاملEvolution of Lead Titanate Nanostructures from Nanoparticle Self-Assembly
Ferroelectric nanostructures are promising building blocks for advanced electromechanical devices. In this paper, we report a hydrothermal synthesis of PbTiO3 nanoring and nanoring-nanowire hybrid structures. Evolution of the nanoring structure was suggested to be caused by the self-directed assembly of PbTiO3 nanoparticles, where polarization of the ferroelectric nanoparticles might direct the...
