The lead magnesium niobate [Pb(Mg1/3Nb2/3)O-3 or PMN], and its solid solutions with lead titanate (PbTiO3 or PT), are of great interest because of their high electromechanical properties. At large PMN content, these materials exhibit relaxor characteristic ...
This paper reviews deposition, integration. and device fabrication of ferroelectric PbZrxTi1-xO3 (PZT) films for applications in microelectromechanical systems. As examples, a piezoelectric ultrasonic micromotor and pyroelectric infrared detector array are ...
The continuous downscaling of microelectronic circuits combined with increasing interest in ferroelectric thin films for non-volatile random access memories (FeRAM) is drawing great attention to small ferroelectric thin film structures. There are various c ...
The fabrication and characterization of a microfabricated acoustic Lamb-wave device driven by a piezoelectric PZT (modified lead zirconate titanate Pb(Zr-x,Ti1-x)O-3) sol-gel thin film for use in mass-transport, mass-filtering and fluid-delivery systems ar ...
The influence of ultraviolet (UV) illumination on piezoelectric properties is investigated in lead zirconate titanate (PZT) thin films. It is found that the poling procedure is more effective when the film is exposed to a broadband UV light in the presence ...

A phenomenological approach is proposed describing both nonlinearity and frequency dispersion in dielectric and piezoelectric properties of lead zirconate titanate, Pb(Zr,Ti)O-3 (PZT), thin films and ceramics. The approach couples the frequency dependent r ...
PZT thin films for memory applications are known to lack sufficient resistance versus polarization fatigue when used together with platinum. One possible solution for this problem is to use conductive oxides like La1-xSrxCoO3 (LSCO) as an electrode. In thi ...
The printing of lead zirconate titanate (PZT, Pb(Zr,Ti)O-3) piezoelectric thick films on silicon substrates is being studied for potential use as microactuators, microsensors, and micro.. transducers. A fundamental challenge in the fabrication of useful PZ ...
The incorporation of up to 40 % lead excess into the perovskite lattice of Pb(Zr,Ti)O-3 (PZT) has been investigated. Three independent chemical composition analysis methods confirmed the correct determination of the lead excess, present as Pb2O3. High reso ...
