Nonlinear piezoelectricity in epitaxial ferroelectrics at high electric fields.
Nonlinear effects in the coupling of polarization with elastic strain have been predicted to occur in ferroelectric materials subjected to high electric fields. Such predictions are tested here for a PbZr0.2Ti0.8O3 ferroelectric thin film at electric fields in the range of several hundred MV/m and strains reaching up to 2.7%. The piezoelectric strain exceeds predictions based on constant piezoe...
متن کاملPiezoelectricity in the dielectric component of nanoscale dielectric-ferroelectric superlattices.
The origin of the functional properties of complex oxide superlattices can be resolved using time-resolved synchrotron x-ray diffraction into contributions from the component layers making up the repeating unit. The CaTiO3 layers of a CaTiO3/BaTiO3 superlattice have a piezoelectric response to an applied electric field, consistent with a large continuous polarization throughout the superlattice...
متن کاملAnisotropic nonlinear dielectric response of relaxor ferroelectrics
The anisotropy of the nonlinear static dielectric response of inorganic relaxor ferroelectrics of lead magnesium niobate PMN type is studied in the framework of the spherical random bond–random field model. Assuming that the shape of a polar nanoregion PNR and thus its dipole moment is modified by the action of homogeneous lattice strains, the anisotropic part of the interaction between the PNR...
متن کاملNew Dielectric Resonances in Mesoscopic Ferroelectrics
A new type of dielectric resonance has been observed in several mixed ferroelectrics, KTa12xNbxO3 (KTN), K12xLixTaO3 (KLT), and PbMg1y3Nb2y3O3 (PMN), also known as relaxor ferroelectrics. This resonance and its metastability (persistence over long periods of time) in KTN in the paraelectric phase provides clear evidence, in relaxors, for the presence of permanent polar nanoregions and strong po...
متن کاملHierarchical dielectric orders in layered ferroelectrics Bi2SiO5
Electric dipole engineering is now an emerging technology for high electron-mobility transistors, ferroelectric random access memory and multiferroic devices etc. Although various studies to provide insight into dipole moment behaviour, such as phase transition, order and disorder states, have been reported, macroscopic spontaneous polarization has been mainly discussed so far. Here, visualizat...
