Strontium Bismuth Titanate is a very promising material for high temperature piezoelectric applications, its elevated ferroelectric phase transition (530°C), linear piezoelectric properties under low field and relatively low room temperature conductivity ( ...
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 ...
We have studied deposition by in-situ reactive sputtering of ferroelectric Pb(ZrxTi1-x)O3 (PZT) thin films on Pt and RuO2 electrodes, using temperatures in the 490-620°C range. Nucleation on the electrode was found to be of prime importance for the formati ...
The effect of acceptor (Na, Mg, Fe) and donor (Nb,Ta) dopants on the switching properties of Pb(Zr0.53Ti0.47)O-3 (PZT) thin films with Pt electrodes was investigated for broad dopant concentration ranges. The effect of dopants on endurance was found to be ...
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 study was conducted on the effects of microstructure, atmosphere, and several dopants on the electrical conductivity of bismuth titanate (Bi4Ti3O12, BIT), Increased grain size increased the conductivity in undoped BIT as did acceptor dopants that substit ...
Leakage conduction of Pt-Pb(ZrXTi:(1-X))O-3-Pt capacitors is studied by means of different measuring techniques and analyzed in terms of semiconductor properties of the system. Based on the experimental data, it is concluded that two different regimes of c ...
The effects of niobium doping on the hysteresis parameters of sol-gel Pb-1.1-x/2(Zr0.53Ti0.47)(1-x)NbxO3 (0 < x < 0.05) have been reported fbr two sets of films with analogous grain size and degree of (111) texture but with different surface microstructure ...
The switching, fatigue and rejuvenation phenomena of ferroelectric PZT thin films with differently processed electrode-PZT interfaces and of different thicknesses have been investigated. The ferroelectric contribution to the switching parameters has been i ...
