Enhanced Energy Storage Properties of the Relaxor and Antiferroelectric Crossover Ceramic Enabled by a High Entropy Design.

ABSTRACT: In this work, we introduce a high entropy effect in designing a relaxor ferroelectric (RFE)-antiferroelectric (AFE) crossover ceramic by incorporating a high entropy relaxor-like oxide (Pb_0.25Ba_0.25Sr_0.25Ca_0.25)TiO₃ with antiferroelectric NaNbO₃. The results show that the relaxor ferroelectricity of the system is enhanced with increasing NaNbO₃, and when the new composition reaches the highest configurational entropy, stable energy storage properties can be achieved. This is enabled by a high breakdown strength due to the small grain size and stable slim ferroelectric hysteresis loop with high efficiency due to entropy-stabilized short-range ordered polar nanoregions (PNRs). These findings showcase the potential o
