Published: Extraordinarily Large Contribution Ratio of Ferroelastic Domain Switching to Piezoresponse in Monoclinic (K, Na)NbO3 Films

Our paper entitled “Extraordinarily Large Contribution Ratio of Ferroelastic Domain Switching to Piezoresponse in Monoclinic (K, Na)NbO₃ Films” has been published in Adv. Electron. Mater. We found that the extrinsic contribution to the piezoresponse in (111)epitaxial monoclinic (K, Na)NbO₃ films is extraordinarily large, over 100% under moderate electric fields.
