In situ X-ray diffraction studies on the piezoelectric response of PZT thin films

Abstract

International audiencePiezoelectric properties of randomly oriented self-polarized PbZr0.50Ti0.50O3 (PZT) thin films were investigated using in situ synchrotron X-ray diffraction. Possibilities for investigating the piezoelectric effect using microsized hard X-ray beams are demonstrated and perspectives for future dynamical measurements on PZT samples with variety of compositions and thicknesses are given. Studies performed on the crystalline [100, 110] directions evidenced piezoelectric anisotropy. The piezoelectric coefficient d(33) was calculated in terms of the lab reference frame (d(perp)) and found to be two times larger along the [100] direction than along the [110] direction. The absolute values for the d(perp) amount to 120 and 230 pm/V being in good agreement with experimental and theoretical values found in literature for bulk PZT ceramics. (C) 2016 Elsevier B.V.

Piezoelectric Properties of Pb1−xLax(Zr0.52Ti0.48)1−x/4O3 Thin Films Studied by In Situ X-ray Diffraction

“…in situ X-ray diffraction experiments were performed at the DiffAbs beamline at SOLEIL synchrotron (St Aubin, France) [23,24]. The incident monochromatic 10 keV X-ray beam was collimated to a size of 50 µm using a pinhole placed about 20 cm upstream of the sample.…”

Crystallographic contributions to piezoelectric properties in PZT thin films

“…Our previous report demonstrated that the piezoelectric properties of polycrystalline PZT thin films was larger than that of epitaxial PZT thin films 16 . In this study, to understand the crystallographic factors contributing to the macroscopic piezoelectric properties, we performed in-situ X-ray diffraction (XRD) measurements 18–24 on PZT thin films using a synchrotron radiation source. Here, we demonstrate one of the first comparative discussions that evaluates the macroscopic piezoelectric properties and the microscopic deformation of crystal structures of epitaxial and polycrystalline Pb(Zr,Ti)O 3 (PZT) thin films.…”

Effect of polarization switching on piezoelectric and dielectric performance of electrospun nanofabrics of poly(vinylidene fluoride)/Ca–Al LDH nanocomposite

“…The most popular materials are ZnO, BaTiO 3 , AlN, and lead zirconate titanate. [3][4][5][6][7][8] Even though the aforementioned materials exhibit high piezoelectric performance, they lack flexibility and environment-friendliness. In this regard, poly(vinylidene fluoride) (PVDF)-based systems have gained tremendous popularity due to their flexibility, mechanical stability, thermal stability, and chemical inertness.…”
