“…From lead zirconate [55][56][57][58] to lead titanate [59][60][61][62][63] through several intermediate compositions [64][65][66][67][68], PZT has been studied under pressure. Among the numerous interesting results in this field, a high-pressure form of ferroelectricity has been calculated and observed in PbTiO 3 [59,60] at room temperature.…”

Strain engineering aims to take advantage of the stress field imposed by substrates on thin films. It requires an understanding of the consequences of stress fields on the physical properties of the deposited materials. This is achieved in ferroelectric thin films through the use of misfit-strain phase diagrams that show the stability regions for the possible phases. These encompass bulk phases as well as new ones exhibiting symmetries that are not present in the bulk. For the solid solution lead zirconate-lead titanate, Pb(Zr 1-x Ti x )O 3 , monoclinic phases found in the bulk morphotropic phase boundary region and associated to concentrations exhibiting the highest properties can be stabilized on a wider range of composition in thin films. In addition, phases of lower symmetry can be stabilized through the use of anisotropic biaxial stress fields, generated by orthorhombic substrates for example. Another crucial aspect of the influence of biaxial stress fields is the generation of domain structures. Theoretical tools as well as experimental verifications have provided much insight on the underlying physics. We, therefore, present here an overview of the influence of both iso-and anisotropic biaxial stress fields on the structures and properties of ferroelectric thin films exemplified on Pb(Zr 1-x Ti x )O 3 .

“…The superior properties of PZT thin films are ascribed to their extraordinary dielectric and piezoelectric behaviors around the morphotropic phase boundary (MPB, about Zr:Ti=52:48) where the properties are enhanced. 5,6 Noheda et al have suggested that the enhanced dielectric and piezoelectric properties around the MPB are due to the formation of an intermediate monoclinic phase. [7][8][9] The presence of charged defects in ferroelectrics strongly influences polarization, aging, conductivity, and fatigue.…”

Pb(Zr1-xTix)O3 (PZT) thin films near phase morphotropic phase boundary were deposited on (Pb0.86La0.14)TiO3-coated glass by radio frequency sputtering. A retrieved analysis shows that the lattice parameters of the as-grown PZT thin films were similar to that of monoclinic PZT structure. Moreover, the PZT thin films possessed refractive index as high as 2.504 in TE model and 2.431 in TM model. The as-grown PZT thin film had one strong absorption peak at 632.6 nm, which attributed to lead deficiency by quantitative XPS analysis. From the attractive properties achieved, electro-optic and photovoltaic characteristic of the films were carried out

“…It is known that the PZT features extremely large κ at the morphotropic phase boundary occurring near x = 0.52 [9]. The dielectric constant of the PZT can become as high as 3850, depending upon orientation and doping.…”
