Abstract
We have synthesized the PZT and Nb doped PZT samples using solid state reaction method. XRD studies clearly depict that there is no impurity phase present in the samples. Dielectric measurements show that the dielectric constant was below 500 as required for ferroelectric generator (FEG) applications. Ferroelectric measurements show that the remnant polarization for all samples is above 25 µC/cm2. We have also achieved high density to samples to become good candidate for FEG applications.

Output/Outcome of the Project
Output/Outcome of the project
|
we have delivered 21 samples (PZT 95/5, PZT 95/5 + 2% Nb and PZT 95/5 + 2.5% Nb) to TBRL on 18/09/2017 and completed the performance 1st milestone.
Second, we have delivered 21 samples (against the 50% samples committed to complete the performance milestone 2 under the project) and completed both the milestones of the CARS project.
