TL;DR: In this paper, the influence of laser fluence on transfer of material in solid, fragmented and molten state is investigated during femtosecond LIFT of initially solid layers of thermoelectric bismuth selenide (Bi2Se3), piezoelectoric lead zirconate titanate (PZT) and magnetostrictive Terfenol-D.

TL;DR: In this article, the authors examined bulk piezoelectric ceramics with functional gradients of composition in order to produce large strains and confirmed the Curie temperature of each layer of the functionally graded ceramic through depoling.
Abstract: Piezoelectric ceramics are widely used in industry in such devices as transducers and actuators. While bulk ceramics perform well in most applications, they are limited in use as actuators where large strains are needed. This research examines bulk piezoelectric ceramics with functional gradients of composition in order to produce large strains. Layered lead zirconate titanate ceramics were centrifugally cast with compositional gradients from Pb(Zr 0.50 Ti 0.50 )O 3 to Pb(Zr 0.45 Ti 0.55 )O 3 . X-ray diffraction was used to confirm the unpoled state of each layer of the functionally graded ceramic. X-ray diffraction and d 33 measurements were made to confirm the Curie temperature of each layer of the functionally graded ceramic through depoling. Energy dispersive spectroscopy (EDS) was performed to determine the composition of each layer in the ceramic.

TL;DR: In this paper, the photochemical reaction with a variety of metal salts on a polarizable semiconductor, lead zirconate titanate (PZT 30/70), was investigated.
Abstract: In this work, we have investigated the photochemical reaction with a variety of metal salts on a polarizable semiconductor, lead zirconate titanate (PZT 30/70 [111]). The exact position of the band edges can influence properties such as the width of the space-charge region and barriers for charge injection, which play an important role in devices built with such materials such as FeRAM and MLC. Observations show that there can be metal deposition on positive domains or photodecomposition on negative domains. The exact reaction was found to be dependent on the reduction potential of the cation and whether a nitrate or chloride salt was used. We show that for certain cations such as Fe2+, with a reduction potential near the edge of the conduction band of the PZT, either reduction or photodecomposition can happen. This effect can be explained because of the presence of an uncertainty in the location of the band edges at the surface of the PZT. The exact position of these edges is determined by the Femi level...
