Boosting energy storage performance with lead-free relaxor ferroelectric in BNT-based ceramics <i>via</i> introducing scheelite La₂WTiO₈

Abstract

Combining the chalcocite structure with the scheelite structure reduces the domain size and leads to the formation of PNRs. And the introduction of LWT tunes the temperature region between T f and T b of the relaxing ferroelectrics to near RT.
