Enhancing properties of lead-free ferroelectric BaTiO3 through doping
Journal of the European Ceramic Society, 2022 The substitution on either the A-or B -site of ferroelectric perovskites by aliovalent elements has a profound influence on their properties. Donor doping “softens” ferroelectrics, whereas acceptor doping “hardens” them. The charge compensation mechanisms

Misfit strain dependence of ferroelectric and piezoelectric properties of clamped (001) epitaxial Pb(Zr0.52,Ti0.48)O3 thin films \ud [PDF]
, 2011 A study on the effects of the residual strain in Pb(Zr0.52Ti0.48)O3 (PZT) thin films on the ferroelectric and piezoelectric properties is presented. Epitaxial (001)-oriented PZT thin film capacitors are sandwiched between SrRuO3 electrodes. The thin film

Universal Properties of Ferroelectric Domains
Physical Review Letters, 2009 Basing on Ginzburg-Landau approach we generalize the Kittel theory and derive the interpolation formula for the temperature evolution of a multi-domain polarization profile P(x,z). We resolve the long-standing problem of the near-surface polarization behavior in ferroelectric domains and demonstrate the polarization vanishing instead of usually assumed

Multiferroic hexagonal ferrites (h-RFeO$_3$, R=Y, Dy-Lu): an experimental review [PDF]
, 2014 Hexagonal ferrites (h-RFeO$_3$, R=Y, Dy-Lu) have recently been identified as a new family of multiferroic complex oxides. The coexisting spontaneous electric and magnetic polarizations make h-RFeO$_3$ rare-case ferroelectric ferromagnets at low ...

Morphology and Ferroelectric Properties of Semiconducting/Ferroelectric Polymer Bilayers [PDF]
Macromolecules, 2019 Bilayers of the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE) on semiconducting poly(3-hexyl thiophene) substrates have been prepared by sequential spin-coating. Here, we present a study of the polarization of this ferroelectric/semiconducting bilayer as a function of the semiconductor thickness by piezoresponse force ...
