Abstract
- PbZrO<subscript>3</subscript> has been broadly considered as a prototypical antiferroelectric material for high-power energy storage. A recent theoretical study suggests that the ground state of PbZrO<subscript>3</subscript> is threefold-modulated ferrielectric, which challenges the generally accepted antiferroelectric configuration. However, such a novel ferrielectric phase was predicted only to be accessible at low temperatures. Here, we successfully achieve the room-temperature construction of the strongly competing ferrielectric and antiferroelectric state by strain-mediated phase separation in PbZrO<subscript>3</subscript>/SrTiO<subscript>3</subscript> thin film. We demonstrate that the phase separation occurs spontaneously in quasi-periodic stripe-like patterns under a compressive misfit strain and can be tailored by varying the film thickness. The ferrielectric phase strikingly exhibitsa threefold modulation period with a nearly up-up-down configuration, which could be stabilized and manipulated by the formation and evolution of interfacial defects under applied strain. The present results construct a fertile ground for further exploring the physical properties and applications based on the novel ferrielectric phase. There is a desire to know how the threefold ferrielectric coexists with the antiferroelectric phase. Here, the authors realize a threefold-modulated ferrielectric phase regulated by strain-mediated phase separation in PbZrO<subscript>3</subscript> thin film. [ABSTRACT FROM AUTHOR]
