The optical properties of lead zirconate titanate (PZT) thin films deposited on ZnO were studied by m-lines spectroscopy. In order to retrieve the refractive index and the thickness of both layers from the m-lines spectra, we develop a numerical algorithm for the case of a two-layer system and show its robustness in the presence of noise. The sensitivity of the algorithm of the two-layer model ...

Title of dissertation: LEAD ZIRCONATE TITANATE THIN FILMS FOR PIEZOELECTRIC ACTUATION AND SENSING OF MEMS RESONATORS Brett Harold Piekarski, Doctor of Philosophy, 2005 Dissertation directed by: Professor Donald DeVoe Department of Mechanical Engineering and Bioengineering Graduate Program This research is focused on examining the potential benefits and limitations of applying sol-gel lead zirco...

In this paper we present a cost effective method to fabricate flexible, high density piezoelectric tape, and expl'ore its potential application as a new type of Lamb wave phased array for Structural Health Monitoring (SHM) through simulating the Lamb wave propagation generated from single element and multielement arrays. The piezoelectric tape consists of many patterned and densely packed PZT (...

Modern high-frequency applications critically depend on the availability of data dielectric properties functional materials in microwave and mm-wave range. This paper investigates response polycrystalline lead zirconate titanate (PZT) thin films prepared by solution deposition at frequencies between 10 MHz 70 GHz temperatures 305 K to 395 measuring S-parameters coplanar waveguides (CPW). The re...

Comparative study of the of azo Dyes (as a class important organic pollutants photodegradation process) in aqueous solution employing H2 O2 /UV and K2 S2 O8 /UV systems in a photochemical reactor were investigated. Lead zirconate titanate [Pb (Zr0.58Ti0.42) O3 ] (PZT) nanocatalyst was synthesized via the sol-gel method. Then, photocatalytic properties of dopant type on PZT were determined in a ...
