Abstract

The tunable electrocaloric effect (ECE) is reported in BaZr_0.2Ti_0.8O₃ homogeneous bilayer thick films through a minor modification during fabrication process. Two types of sintering aids, LiBiO₂ and the mixture of PbO and B₂O₃, were used to lower the sintering temperature, improving the sintering condition. Compared with the mixture of PbO and B₂O₃ the LiBiO₂ is demonstrated to be more effective in inducing ECE enhancement in the BaZr_0.2Ti_0.8O₃ bilayer thick films, where a large electrocaloric temperature change of −3.9 K under 10 MV m⁻¹ around room temperature can be observed. The result reveals the potential of fine tuning additives in improving the electrocaloric effect, providing an effective and affordable route to realize large ECE under low electric fields.
