Lead zirconate titanate (PZT) is one of the most widely studied piezoelectric materials, mainly because its 'mysterious' relationship between so-called morphotropic phase boundary (MPB) and strong coupling factor. Using results from a pair distribution function analysis, this paper examines how complex local structure in PZT affects long-range average across MPB. A monoclinic M C type discovered PZT. first-order transformation components both structures explains sudden change effect around...
The physical origin of the piezoelectric effect has been focus much research work. While it is commonly accepted that origins piezoelectricity may be intrinsic (related to change lattice parameters) and extrinsic movement domain walls), their separation often a challenging experimental task. Here in situ high-resolution synchrotron X-ray diffraction combined with new data analysis technique characterize parameters microstructure PbZr 1− x Ti O 3 ( = 0.45) crystal under an external electric...
Antiferroelectric perovskites form an important family of functional electric materials, which have high potential in energy storage and conversion applications. However, a full understanding their crystal structural formation is still lacking. ${\mathrm{PbZrO}}_{3}$-based materials can serve as model system for investigation, not only because ${\mathrm{PbZrO}}_{3}$ was the first discovered antiferroelectric, but also it undergoes typical phase transition sequence from high-temperature...
$\mathrm{Pb}{\mathrm{Zr}}_{1\ensuremath{-}x}{\mathrm{Ti}}_{x}{\mathrm{O}}_{3}$ exhibits an antiferroelectric-ferroelectric phase boundary at the composition $x\ensuremath{\sim}0.06$. Around this boundary, several questions need to be answered, such as stabilizations of different phases with a small amount compositional difference, sequence transitions, coexistence crystal structures, and potential applications. In work, we have carried out systematic structural investigations single crystals...
PbZr1-xTixO3, which has abundant structural variations in the corresponding physical properties, been used a large variety of applications. To understand effect structure on its high-performance piezoelectric local and average structures are studied. Total scattering data have obtained from high-energy synchrotron powder diffraction experiments at 20 K 300 K. Using reverse Monte Carlo method, information cation displacements extracted X-ray Pair Distribution Function data. This suggests that...
In order to reduce the ignition energy of tantalum nitride film transducer, a new type exchangers bridge area was designed in this paper, and it fabricated by MEMS technology. The parameters voltage, energy, as well action time were tested. experimental results showed that terms time, value element lower than conventional area. addition, performance can be reduced many
Domain boundaries in ferroic materials are found to have various physical properties not observed the surrounding domains. Such differences can be enhanced and bring promising functionalities when centrosymmetric nonpolar encounter polar domain boundaries. In this work, a tunable boundary is discovered an antiferroelectric single crystal. Under small stress or electric field, density, volume, polarity of successfully controlled.
Voltage-controlled perpendicular magnetic anisotropy (PMA) switching is one of the crucial challenges in realizing fast, compact, lightweight devices. In article number 1801639, Ziyao Zhou, Ming Liu, and co-workers achieve reversible PMA with 4 V through ionic-liquid (IL) gating. The illustration shows IL-gating-induced spin reorientation (SRT), which promising new-generation spintronic
