Abstract
(001)pc textured K0.5Na0.5NbO3 (KNN) ceramic was found to exhibit a 65% improvement in the
longitudinal piezoelectric response as compared to its random counterpart. Piezoresponse force
microscopy study revealed the existence of larger 180 and non-180 domains for textured ceramic
as compared to that of the random ceramic. Improvement in piezoresponse by the development of
(001)pc texture is discussed in terms of the crystallographic nature of KNN and domain morphology.
A comparative analysis performed with a rhombohedral composition suggested that the improvement
in longitudinal piezoresponse of polycrystalline ceramics by the development of (001)pc texture is
limited by the crystal structure.
