Piezoelectric softening by Nb substitution in (Ba,Pb)ZrO

Dragan Damjanovic, Nava Setter, Alberto Biancoli, Nicola Marzari, David Bahati

Donor doping is commonly applied for softening of the piezoelectric and dielectric properties and facilitation of polarization switching in the ubiquitous Pb(Zr,Ti)O-3 [PZT] ceramics. The origin of the donor-dopant effects is not entirely clear. (Pb,Ba)ZrO ...

Symmetry breaking in hexagonal and cubic polymorphs of BaTiO3

Dragan Damjanovic, Alberto Biancoli

BaTiO3 appears in cubic and hexagonal variants, both of which are centrosymmetric. Samples of cubic BaTiO3 are known to exhibit breaking of the centric symmetry locally and globally. It has been proposed that the local symmetry breaking originates in polar ...

Breaking of macroscopic centric symmetry in paraelectric phases of ferroelectric materials and implications for flexoelectricity

Dragan Damjanovic, Alberto Biancoli

A centrosymmetric stress cannot induce a polar response in centric materials; piezoelectricity is, for example, possible only in non-centrosymmetric structures. An exception is meta-materials with shape asymmetry, which may be polarized by stress even when ...
