Phase Structures, Electromechanical Responses, and Electrocaloric Effects in K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub> Epitaxial Film Controlled by Non-Isometric Misfit Strain

Environmentally friendly lead-free K<sub>1-x</sub>Na<sub>x</sub>NbO<sub>3</sub> (KNN) ceramics possess electromechanical properties comparable to lead-based ferroelectric materials but cannot meet the needs of device miniaturization, and the corresponding thin fil...
