Diverse device applications for lead zirconate titanate (PZT) ceramics in thick-film form are currently in active development. In the present study, the particle dispersion properties of thick-film ink formulations containing PZT powder have been determine ...
The domain nucleation and growth during polarization switching in Pb(Zr,Ti)O-3 (PZT) ferroelectric thin film capacitors with Pt top (TE) and bottom electrodes (BE) were studied by means of atomic force microscopy (AFM). The experimental configuration used ...
This paper reviews deposition, integration, and device fabrication of PbZrxTi1-xO3 (PZT) films for applications in micro-electromechanical systems. An ultrasonic micromotor is described as an example. A summary of the published data on piezoelectric proper ...
The ac field dependence of dielectric and piezoelectric response of sol-gel derived Pb(Zr,Ti)O(3)thin films is presented. The nonlinear response of dielectric polarisation and piezoelectrically induced strain at sub-switching fields was studied in terms of ...
Mechanisms of polarization switching and fatigue in (Pb, La)(Zr, Ti)O-3 (PLZT) films are studied by comparative analysis of degradation and leakage conduction of PLZT capacitors with Pt, SrRuO3 (SRO), and layered Pt/SRO (80/5 nm) electrodes. It is found th ...
In situ reactively sputter deposited, 300-nm-thick Pb(Zrx,Ti1-x)O3 thin films were investigated as a function of composition, texture, and different electrodes (Pt,RuO2). X-ray diffraction analysis, ferroelectric, dielectric, and piezoelectric measurements ...
The effective piezoelectric transverse coefficient e(31,f) was measured on various lead zirconate-titanate (PZT) and aluminum nitride thin films. The measurement set-up is based on the collection of the electric charges created by the forced deflection of ...
The shape of the grains and the granulometry distribution of the PZT powder are the main factor influencing the densification. In addition, we shown that a higher concentration of PZT powder in the ink with a right rheology of the ink improves the density ...
The integration of piezoelectric Pb(Zr,Ti)O-3 thin films on silicon substrates for ultrasonic motor applications is reviewed. With suitable buffer and bottom electrode layers the problems due to high processing temperatures in oxygen ambient can be handled ...
The effects of donor (Nb, Ta) and acceptor (Na, Mg, Fe) dopants on the crystallization mechanism of PZT thin films were investigated. The parameters which control microstructure development were found to be different for donors and accepters. Lead stoichio ...
