From: Observation of solid-state bidirectional thermal conductivity switching in antiferroelectric lead zirconate (PbZrO3)

Fig. 1

a Reciprocal space map of the PbZrO3 440/280O and DyScO3 332O reflections demonstrating epitaxial growth and the presence of ferroelastic domains in the epitaxial film. b Polarization-electric field hysteresis response for the epitaxial PbZrO3 film showing antiferroelectric switching. c 2θ-ω XRD pattern for the polycrystalline PbZrO3 film. d Channeling-contrast backscatter electron micrograph of the polycrystalline PbZrO3 film. The arrows indicate the locations of clearly resolved ferroelastic domains. e Phase diagram for lead zirconate titanate (PbZr1−xTixO3, PZT) recreated from ref. 27. f Schematic of dipole orientation across antiferroelectric to ferroelectric (AFE-to-FE) and antiferroelectric to paraelectric (AFE-to-PE) phase transitions.
