Key Points

The study shows a significant enhancement in the negative electrocaloric effect due to Sn doping.
An increased entropy change (Δ S) contributes to reducing the energy barrier between antiferroelectric and ferroelectric states.
Sn doping leads to improved polarization, enhancing thermal responses in PbHfO3 films.
The findings highlight the potential for optimizing electrocaloric materials in thermal management applications.

Implication

This research demonstrates enhanced electrocaloric effect through Sn doping, suggesting improved polarization in antiferroelectric films.

Abstract

Sn 4+ doping in PbHfO 3 films lowers the antiferroelectric–ferroelectric (AFE–FE) energy barrier, improving polarization. By increasing the entropy change (Δ S ), it significantly enhances the negative electrocaloric effect (NECE).
