Experimental and Numerical Investigation on Photostrictive Materials for Mems Application
… La) (Zr, Ti) O3 ceramic doped with WO3, called PLZT, is one of the photostrictive ceramics which has an advantage to use as a wireless remote control over traditional actuators. The traditional actuators require wire connections to transmit the control signal; these wires yield noise by the …

Dielectric and Ferroelectric Properties of Lead Lanthanum Zirconate Titanate Thin Films for Capacitive Energy Storage
… ub>(Zr<sub>y</sub>Ti<sub>1-y</sub>)O<sub>3</sub> (PLZT, x/y/1-y) relaxor thin films deposited on silicon (Si) and nickel (Ni) substrates in a range of thickness with different bottom electrodes, e.g. Platinum (Pt) and LaNiO<sub>3</sub> (LNO). The final fabricated PLZT film capacitors will show …

Microcomputer control of a three-dimensional stereoflouroscope
… visualization has been achieved by using PLZT crystal technology. The computer will control two grid-pulsed x-ray sources, an image intensifier, a solid-state video camera, a video monitor and the PLZT goggles to provide a stereoscopic image. Dose reduction should be obtained through the …

Phase development and texture for lead-based perovskite thin layers prepared by sol-gel processing
… Ferroelectric La-modified Pb(Zr,Ti)O$\sb3$ (PLZT) and antiferroelectric PbZrO$\sb3$ (PZ) were chosen as materials which could be potentially used in integrated devices, including, sensors, actuators, and memory applications. Emphasis was placed on determining (i) the processing conditions …

Dielectric noise spectroscopy of relaxor ferroelectrics
… dynamics of the relaxor ferroelectric material PLZT(B/65/35) in the ""frozen"" state. A relaxor ferroelectric is a material which has local ferroelectric order on the 1 Onm scale (nanodomains) but on longer scales the material is disordered. The nanodomains appear to go through a freezing …

Structure-Property Relations on Strain-Mediated Multiferroic Heterostructures
… Epitaxial (Pb0.98La0.02)(Zr0.95Ti0.05)O3 (PLZT) thin films were deposited on differently oriented SrTiO3 single crystal substrates. A thickness dependent incommensurate/commensurate antiferroelectric-to-ferroelectric phase transition was identified. The crystal structure, phase transition …

Direct liquid injection metalorganic chemical vapor deposition of ferroelectric PZT films
… showed high dielectric constants, about 700 for PLZT (4/34/66) and about 1200 for PLZT (4/55/45). The dissipation factors, tan 𝜕, for the above films were 0.023 and 0.03, respectively. The electrical fatigue of the typical PZT films showed 70% switched polarization remained after 10¹⁰ cycles. …

Dielectric and electromechanical properties of barium and zirconium co-doped sodium bismuth titanate
… of strain and d₃₃ for polycrystalline PMN and PLZT and single crystal PMN conventional lead electrostrictors. Predominantly ferroelectric room temperature unipolar actuation in polycrystalline NBT-14BT-3NBZ at 0.05 Hz was observed to be linear and non-hysteretic, reaching up to 0.14% strain and …

Lead-free piezoelectric transducers for vibration based energy harvesting devices
Future applications like piezoelectric energy harvesters in addition with increasing environmental awareness ultimately demand novel sophisticated material systems in the field of piezoelectrics as an alternative to the long-established system lead-zirconate-titanate. In this publication …
