Effect of mechanical depoling on piezoelectric properties of Na0.5Bi0.5TiO3 - xBaTiO3 in the morphotropic phase boundary region
Denis, L; Glaum, Julia; Hoffman, Mark; Daniels, John E.; Hooper, Ryan; Tutuncu, Goknur; Forrester, Jennifer; Jones, Jacob L. (Journal article; Peer reviewed, 2018)The effect of mechanical stress on the direct piezoelectric properties of pre-poled (1 − x)(Na0.5Bi0.5)TiO3–xBaTiO3 (NBT–xBT) in the range 4% ≤ x ≤ 13% was studied in situ using a mechanical load frame. Prior to mechanical ... -
Piezoelectric K0.5Na0.5NbO3 Ceramics Textured Using Needlelike K0.5Na0.5NbO3 Templates
Haugen, Astri Bjørnetun; Olsen, Gerhard Henning; Madaro, Francesco; Morozov, Maxim; Tutuncu, Goknur; Jones, Jacob L.; Grande, Tor; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2014)Improved performance by texturing has become attractive in the field of lead-free ferroelectrics, but the effect depends heavily on the degree of texture, type of preferred orientation, and whether the material is a rotator ... -
Rayleigh analysis of dielectric properties in textured K0.5Na0.5NbO3 ceramics
Haugen, Astri Bjørnetun; Morozov, Maxim; Jones, Jacob L.; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2014)Grain texturing is a known method of exploiting the intrinsic dielectric and piezoelectric anisotropy in ferroelectric ceramics. However, the role of crystallographic texture on anisotropic extrinsic contributions including ... -
Residual Stress and Ferroelastic Domain Reorientation in Declamped {001} Pb(Zr0.3Ti0.7)O3 Films
Denis-Rotella, Lyndsey M.; Esteves, Giovanni; Walker, Julian; Zhou, Hanhan; Jones, Jacob L.; Trolier-Mckinstry, Susan (Peer reviewed; Journal article, 2021)Ferroelectric films are often constrained by their substrates and subject to scaling effects, including suppressed dielectric permittivity. In this work, the thickness dependence of intrinsic and extrinsic contributions ... -
Structure and phase transitions in 0.5(Ba0.7Ca0.3TiO3)-0.5(BaZr0.2Ti0.8O3) from -100 degrees C to 150 degrees C
Haugen, Astri Bjørnetun; Forrester, Jennifer S.; Damjanovic, Dragan; Li, Binzhi; Bowman, Keith J.; Jones, Jacob L. (Journal article; Peer reviewed, 2013)The solid solution of (x)Ba0.7Ca0.3TiO3-(1-x)BaZr0.2Ti0.8O3 is known to exhibit high piezoelectric constants. Discrepancies in the reported phase transitions and structure around room temperature, however, have complicated ...
