Which antiferroelectric materials have a good energy storage performance?

Antiferroelectric materials with higher electric field, reduced energy dissipation and lower remanent polarization generally display excellent energy storage performance. In this work, Pb 0.98 La 0.02 (Hf x Sn 1−x) 0.995 O 3 lead-based antiferroelectric ceramics were synthesized by a rolling process.

What is antiferroelectricity?

Antiferroelectricity is a property of a material, and it can appear or disappear (more generally, strengthen or weaken) depending on temperature, pressure, external electric field, growth method, and other parameters.

Are lead-based antiferroelectric ceramics a good energy storage material?

Antiferroelectric materials with higher electric field, reduced energy dissipation and lower remanent polarization generally display excellent energy storage performance. In this work, Pb0.98La0.02 (HfxSn1−x)0.995O3 lead-based antiferroelectric ceramics were synthesized by a rolling process.

Is antiferroelectricity a physical property?

Antiferroelectricity is a physical property of certain materials. It is closely related to ferroelectricity; the relation between antiferroelectricity and ferroelectricity is analogous to the relation between antiferromagnetism and ferromagnetism.

Why are antiferroelectric ceramics used in high energy-density capacitors?

Antiferroelectric ceramics are exploited for applications in high energy-density capacitors due to their reversible electric-field-induced phase transitions. The difference in the fields between the forward and reverse transition is termed electric hysteresis.

What is the difference between a ferroelectric and an antiferroelectric?

In an antiferroelectric, unlike a ferroelectric, the total, macroscopic spontaneous polarization is zero, since the adjacent dipoles cancel each other out.

Antiferro-elektriciteit

De antiferro-elektriciteit is een eigenschap dat bepaalde materialen het vlak van de orde van elektrische dipolen hebben.

Abstract: We successfully developed a high-performance FeFET memory device by integrating ZrO 2 anti-ferroelectric with IGZO channel for the first time. The replacement of conventional HfO 2 ferroelectric by anti-ferroelectric ZrO 2 effectively reduces the coercive field and boosts endurance. Furthermore, the IGZO channel allows for an interlayer free gate stack that lowers …

Ferroelectricity

In physics and materials science, ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field. [1] [2] All ferroelectrics are also piezoelectric and pyroelectric, with the additional property that their natural electrical polarization is reversible.
