Piezoelectric materials have been using widely for various applications like MEMS and energy harvesting. The PZT (PbZr0. 52Ti0.48O3) is one among of all piezoelectric materials, which exhibit vital role for fabrication of devices. The present manuscript is described about PZT powders, which were synthesized by solgel method and yielded powders were annealed at different temperature to get stabilize structure without any impurities phase with help of X-ray diffraction. As a part of structural investigation, Raman spectroscopy have done over the different temperature annealed powders and identify Raman active modes. The band gap energy was found for these nano powders that are increasing with respect to annealing temperature. The microstructure of nano PZT powders has found with help FESEM, which provided the particles size with order of 50-70 nm diameters. Electrical properties i.e., the P-E loop have done on nano PZT, polarization has increased and leakage current also increased for annealed temperatures. The terahertz spectra of PZT results suggested that the absorption coefficient peak found at higher frequency, refractive index peak found lower frequency for annealed PZT samples. The 600 oC is shown maximum dielectric constant & refractive index at 0.6 THz, which is confirmed by the electric properties of PZT. As annealing temperature increases, dielectric and refractive index decreased due to depolarization.

This work introduces a piezoelectric–pyroelectric nanogenerator (P-PNG) based on methylammonium lead iodide (CH3NH3PbI3) incorporated electrospun poly(vinylidene fluoride) (PVDF) nanofibers that are able to harvest mechanical and thermal energies. During the application of a periodic compressive contact force at a frequency of 4 Hz, an output voltage of ∼220 mV is generated. The P-PNG has a piezoelectric coefficient (d 33) of ∼19.7 pC/N coupled with a high durability (60 000 cycles) and quick response time (∼1 ms). The maximum generated output power density (∼0.8 mW/m2) is sufficient to charge up a variety of capacitors, with the potential to replace an external power supply to drive portable devices. In addition, upon exposure to cyclic heating and cooling at a temperature of 38 K, a pyroelectric output current of 18.2 pA and a voltage of 41.78 mV were achieved. The fast response time of 1.14 s, reset time of 1.25 s, and pyroelectric coefficient of ∼44 pC/m2 K demonstrate a self-powered temperature sensing capability of the P-PNG. These characteristics make the P-PNG suitable for flexible piezoelectric–pyroelectric energy harvesting for self-powered electronic devices.

“…For LN crystal determination, this technique can be used to qualitatively characterize the involved defects of LN samples, [22,23] to visualize the intensity of the absorption peaks for doped LN samples in relation to the various doping concentrations [24] and obtain information related to the LN sample bandgap. [25,26] LN crystals are ferroelectric and feature an oxygen-containing octahedral structure; their basic optical absorption edge can be determined from the charge transfer transition energy of oxygen 2p electrons to Nb 5+ empty d orbitals. Therefore, changes in the electron cloud distribution of coordinated oxygen affect the position of the absorption edge.…”

Lithium niobate (LN) is a type of multifunctional dielectric and ferroelectric crystal that is widely used in acoustic, optical, and optoelectronic devices. The performance of pure and doped LN strongly depends on various factors, including its composition, microstructure, defects, domain, and homogeneity. The structure and composition homogeneity can affect both the chemical and physical properties of LN crystals, including their density, Curie temperature, refractive index, and piezoelectric and mechanical properties. In terms of practical demands, both the composition and microstructure characterizations these crystals must range from the nanometer scale up to the millimeter and wafer scales. Therefore, LN crystals require different characterization technologies when verifying their quality for various device applications. Optical, electrical, and acoustic technologies have been developed, including x-ray diffraction, Raman spectroscopy, electron microscopy, and interferometry. To obtain detailed structural information, advanced sub-nanometer technologies are required. For general industrial demands, fast and non-destructive technologies are preferable. This review outlines the advanced methods used to characterize both the composition and homogeneity of LN melts and crystals from the micro-to wafer scale.
