Synergistic Regulation of Piezoelectric-Pyroelectric Multifunctionality in Bi 0.5 Na 0.5 TiO 3 (BNT) Ceramics via High-Entropy Engineering

/N. These results demonstrate that high-entropy engineering can effectively overcome the trade-offs in conventional doping, to synergistically improve the piezoelectric and pyroelectric responses. These results also provide an effective strategy for the development of lead-free multifunctional ceramics applied under high-temperature condition.
