Abstract

Piezoelectric and ferroelectric materials are useful as the active element in non-destructive monitoring devices for high-radiation areas. Here, crystallographic structural refinement (i.e., the Rietveld method) is used to quantify the type and extent of structural changes in PbZr₀_.5Ti₀_.5O₃ after exposure to a 1 MeV equivalent neutron fluence of 1.7 × 10¹⁵ neutrons/cm². The results show a measurable decrease in the occupancy of Pb and O due to irradiation, with O vacancies in the tetragonal phase being created preferentially on one of the two O sites. The results demonstrate a method by which the effects of radiation on crystallographic structure may be investigated.

Crystallographic changes in lead zirconate titanate due to neutron irradiation

Journal Article Henriques, Alexandra ; Graham, Joseph T. ; Landsberger, Sheldon ; ... - AIP Advances

Piezoelectric and ferroelectric materials are useful as the active element in non-destructive monitoring devices for high-radiation areas. Here, crystallographic structural refinement (i.e., the Rietveld method) is used to quantify the type and extent of structural changes in PbZr{sub 0.5}Ti{sub 0.5}O{sub 3} after exposure to a 1 MeV equivalent neutron fluence of 1.7 × 10{sup 15} neutrons/cm{sup 2}. The results show a measurable decrease in the occupancy of Pb and O due to irradiation, with O vacancies in the tetragonal phase being created preferentially on one of the two O sites.

Neutron irradiation effects on domain wall mobility and reversibility in lead zirconate titanate thin films

Journal Article Graham, Joseph T. ; Electronic, Optic and Nano Materials Department, Sandia National Laboratories, Albuquerque, New Mexico 87185 ; Brennecka, Geoff L. ; ... - Journal of Applied Physics

The effects of neutron-induced damage on the ferroelectric properties of thin film lead zirconate titanate (PZT) were investigated. Two sets of PbZr{sub 0.52}Ti{sub 0.48}O{sub 3} films of varying initial quality were irradiated in a research nuclear reactor up to a maximum 1 MeV equivalent neutron fluence of (5.16 {+-} 0.03) Multiplication-Sign 10{sup 15} cm{sup -2}. Changes in domain wall mobility and reversibility were characterized by polarization-electric field measurements, Rayleigh analysis, and analysis of first order reversal curves (FORC). With increasing fluence, extrinsic contributions to the small-signal permittivity diminished. Additionally, redistribution of irreversible hysterons towards higher coercive fields was observed accompaniedmore »« less

Variations in the ferroelectric and piezoelectric properties of lead zirconate titanate ceramics containing Cr/sub 2/O/sub 3/ additions. [0. 05 and 0. 20 wt. percent Cr/sub 2/O/sub 3/]

Technical Report Dullea, Jr, J F

Effects of Cr/sub 2/O/sub 3/ additions to Pb(Zr/sub 0/./sub 52/,Ti/sub 0/./sub 48/) O/sub 3/ (PZT) were investigated by doping with 0.05 and 0.20 wt. percent Cr/sub 2/O/sub 3/ and measuring dielectric, ferroelectric, and piezoelectric properties before and after poling under different conditions for time and temperature. The effects of Cr/sub 2/O/sub 3/ were also studied by recording the current in a poling circuit as a function of an applied dc field increasing at a constant rate. The piezoelectric planar coupling coefficient, k/sub p/, was found to be increased at the low doping level, and decreased slightly at the higher dopingmore »« less
Phonon scattering mechanisms dictating the thermal conductivity of lead zirconate titanate (PbZr_1-_xTi_xO₃) thin films across the compositional phase diagram

Journal Article Foley, Brian M. ; Paisley, Elizabeth A. ; DiAntonio, Christopher ; ... - Journal of Applied Physics

This paper represents a thorough investigation of the thermal conductivity (κ) in both thin film and bulk PbZr_1–xTi_xO₃ (PZT) across the compositional phase diagram. Given the technological importance of PZT as a superb piezoelectric and ferroelectric material in devices and systems impacting a wide array of industries, this research serves to fill the gap in knowledge regarding the thermal properties. The thermal conductivities of both thin film and bulk PZT are found to vary by a considerable margin as a function of composition x. Additionally, we observe a discontinuity in κ in the vicinity of the morphotropic phase boundary (MPB,more »« less

Temperature dependence of field-responsive mechanisms in lead zirconate titanate

Journal Article Chung, Ching-Chang ; Fancher, Chris M. ; Isaac, Catherine ; ... - Journal of the American Ceramic Society

An electric field loading stage was designed for use in a laboratory diffractometer that enables in situ investigations of the temperature dependence in the field response mechanisms of ferroelectric materials. The stage was demonstrated in this paper by measuring PbZr_1-xTi_xO₃ (PZT) based materials—a commercially available PZT and a 1% Nb-doped PbZr_0.56Ti_0.44O₃ (PZT 56/44)—over a temperature range of 25°C to 250°C. The degree of non-180° domain alignment (η₀₀₂) of the PZT as a function of temperature was quantified. η₀₀₂ of the commercially available PZT increases exponentially with temperature, and was analyzed as a thermally activated process as described by the Arrheniusmore »« less
