Emerging antiferroelectric phases with fascinating dielectric, polarization and strain response in NaNbO3-(Bi0.5Na0.5)TiO3 lead-free binary system

Environmentally-benign antiferroelectrics (AFEs) have attracted a great deal of attention in recent years owing to their special structure and polarization/strain-electric field response, exhibiting giant application advantages in multifunctional devices. In this work, a detailed phase diagram in a binary lead-free system between AFE NaNbO3 (NN) and ferroelectric (FE) (Bi0.5Na0.5)TiO3 (BNT) was established according to the measurement of...
