Atomic structural mechanism for ferroelectric-antiferroelectric transformation in perovskite NaNbO3
Sodium niobate (NaNbO3 or NN) is described as "the most complex perovskite system,"which exhibits transitions between, as well as coexistence of, several ferroelectrics (FE) and antiferroelectric (AFE) phases at different temperatures. Recently, solid solutions of NN with stabilized AFE phases(s) have gained attention for energy-related applications, such as high-density energy storage and electro
