“…Since the value of exponent n is the measure of ability of domains in following the electric field direction, lower value indicates poor ability of irreversible domains in this respect. 21 As a consequence, the lower value of n leads to lower hysteresis area as well as lower value of remnant polarization. 16 Also the near linear dependence of ͗A͘ to electric field also suggests occurrence of concurrent nucleation and domain boundary motion, phenomena very well known in KNbO 3 and BaTiO 3 .…”

“…20 Higher value of n means sharper response of domains and hence higher value of polarization. 21 Ferroelectric loops were obtained for electric fields varying from 10 to 54 kV/cm while frequency range covered during measurement was 2-200 Hz. Figures 2͑a͒ and 2͑b͒ show the ferroelectric loops obtained at different f but fixed E o ͑54 kV/cm͒ and different E o but fixed frequency ͑f =2 Hz͒.…”

In this letter, we report the dielectric and ferroelectric (FE) characteristics of potassium sodium niobate (K0.5Na0.5NbO3) single crystals grown by flux method. Orientation analysis of as-grown cubical-shaped crystals was conducted by electron backscattered diffraction technique revealing the ⟨100⟩ crystallographic orientation of two opposing major faces. Annealed crystals were found to exhibit FE orthorhombic to FE tetragonal transition temperature of 200 °C and Curie temperature of 407 °C. Poled ⟨100⟩ oriented crystals had longitudinal piezoelectric constant of 148 pC/N. Dielectric measurement as a function of temperature was conducted to determine the second order parameter in Gibbs free energy expansion. Dynamic hysteresis analysis on these crystals showed the power law relations to be of the form ⟨A⟩∝f0.47Eo−0.85Eo1.45f0.14 and ⟨A⟩∝f0.04Eo below and above the coercive field.

“…These values are comparable with those previously reported for PZT-PZN films. [33][34][35][36][37] The dielectric constant and polarization values for the stack with poly-Si are indicative of 24% improvement compared with the values obtained for the stack without poly-Si. The improvement in the dielectric constant is attributed to reduction of the number of nucleation sites as a result of the poly-Si.…”

The effect of a polycrystalline silicon (poly-Si) seeding layer on the properties of relaxor Pb(Zr 0.53 ,Ti 0.47 )O 3 -Pb(Zn 1/3 ,Nb 2/3 )O 3 (PZT-PZN) thin films and energy-harvesting cantilevers was studied. We deposited thin films of the relaxor on two substrates, with and without a poly-Si seeding layer. The seeding layer, which also served as a sacrificial layer to facilitate cantilever release, was found to improve morphology, phase purity, crystal orientation, and electrical properties. We attributed these results to reduction of the number of nucleation sites and, therefore, to an increase in relaxor film grain size. The areal power density of the wet-based released harvester was measured. The power density output of the energy harvester with this relaxor composition and the poly-Si seeding layer was 325 lW/cm 2 .

“…By plotting ͗A͘ against f at fixed E 0 , one obtains the exponent m. The exponent n can be obtained by plotting ͗A͘ against E 0 at fixed f. 11 This method can be repeated for all the cases studied here to extract the magnitude of exponent m and n. After obtaining f-exponent m and E 0 -exponent n, the scaling of hysteresis area ͗A͘ against frequency f and field amplitude E 0 can be obtained as shown in Figs. 8͑a͒-8͑d͒.…”

In this paper, we report the dielectric and ferroelectric response of compositionally graded bilayer and trilayer composites consisting of BaTiO 3 ͑BT͒ and 0.975BaTiO 3 -0.025Ba͑Cu 1/3 Nb 2/3 ͒O 3 ͑BTBCN͒. Two types of graded bilayer samples were synthesized, one with same thickness of BT and BTBCN while other with different layer thicknesses. The graded trilayer sample consisted of BT layer sandwiched between two BTBCN layers of equal thickness. Scanning electron microscopy and transmission electron microscopy images showed a sharp interface with needle-shape domains across the interface. The domain size on BT side was found to be larger than that on BTBCN side. The temperature dependence of dielectric response for all composite systems was found to exhibit shifting in characteristic Curie peak compared to constituent material which was associated to coupling between layers. Moreover, the differences in grain size, tetragonality, domain mobility of each layer was found to perturb the electrical response of composite. The polarization mismatch between uncoupled BT and BTBCN established internal electric field in composite specimen and defined new polarization states in each layer by perturbing free energy functional of the composite specimen. Dynamic hysteresis behaviors and power-law scaling relations of all specimens were determined from polarization-electric field hysteresis loop measurements as a function of frequency. All systems were found to exhibit similar dynamic scaling relationships. Hysteresis area ͗A͘, P r , and E C decreased with increasing frequency due to delayed response but increased with increasing applied electric field due to enhancement of driving force. Trilayer system was found to exhibit strong internal-bias field and double hysteresis behavior. The coupling effect resulting due to polarization mismatch between layers had substantial influence on the dynamic hysteresis behavior and power-law scaling relations.
