Ferroelectric domain pattern and piezoresponse (d33) versus DC bias voltage for the BCZT nanocrystalline powder.

Local piezo-response for lead-free Ba0.9Ca0.1Ti0.9Zr0.1O3 electro-ceramic by switching spectroscopy

“…4 (e). From the butterfly curve showed in panel 4 (d), the effective piezoelectric coefficient (d 33 ) value 35 was estimated through the following equation of the law of converse of piezoelectric effect 32,[36][37][38] : (1) where D is the measured value of piezoelectric displacement, V is the applied voltage, and D 1 and V 1 are the piezoelectric displacement and applied voltage of the intersection …”

Ferroelectric and piezoelectric properties of Ba0.85Ca0.15Ti0.90Zr0.10O3 films in 200 nm thickness range

“…The value of d 33 increased with increasing grain size (The wide variation in d 33 may be verified further with the communicated “”). It should be noted that different localized piezoelectric responses from piezoelectric grains having different grain size were also reported earlier . Since the D‐V butterfly curves were unsymmetrical, obtaining a constant d 33 on either side of the voltage axis (+ve or −ve) was not possible, although the PFM experiments were performed using a properly calibrated PFM measurement set up.…”

Structural, Optical, and Piezoelectric Response of Lead‐Free Ba0.95Mg0.05Zr0.1Ti0.9O3 Nanocrystalline Powder

“…The reports on piezoelectric response of a plethora of perovskite ferroelectric materials, BaTiO 3, LiNbO 3 , K 0.5 Na 0.5 NbO 3 , BCZT etc. at nanoscale has been studied . For instance, Emelianov et al reported the piezoelectric coefficient, ( d 33 ) to be 27 pm/V for BaTiO 3 nanoparticles (spherical shape, diameter of 20–200 nm) with surface‐modified hydroxyl groups.…”

“…at nanoscale has been studied. [18][19][20][21] For instance, Emelianov et al 18 reported the piezoelectric coefficient, (d 33 ) to be 27 pm/V for BaTiO 3 nanoparticles (spherical shape, diameter of 20-200 nm) with surface-modified hydroxyl groups. The reported piezoelectric coefficients (d 33 ) were 17 and 12 pm/V for LiNbO 3 nanoparticles of cube-like shape and spherical shape, respectively.…”

“…Significant piezoelectric response reported at nanoscale was centered on BaTiO 3 and modified BaTiO 3 in which barium is partially replaced by divalent metal such as calcium and titanium by tetravalent metal ion such as zirconium. 18,21 Few reports exist in the literature on the synthesis and characterization of isovalent ion-substituted BaTiO 3 ceramics (where Mg 2+ ion substituted at A-site) that exhibited enhanced dielectric properties. 29 Similar reports exist in the literature on the synthesis, microstructural and electrical properties of Mg 2+ ion substituted at B site (Ti +4 ion) of BaTiO 3 ceramics.…”
