Abstract

Films of solid solution in KNbO₃-NaNbO₃ (KNN) were deposited at 240 °C on (100)_c SrRuO₃//(100)SrTiO ₃ substrates by the hydrothermal method. (K_xNa _1-x)NbO₃ films with x = 0-1.0 were synthesized by changing the fraction of KOH in a solution of KOH and NaOH. The x in (K _xNa_1-x)NbO₃ continuously changed with the volume fraction of KOH, while the deposition amount strongly depended on x. Epitaxial films with {100} orientation were obtained in the entire composition range and their out-of-plane lattice spacing changed with x. All the films showed ferroelectricity and their remanent polarization became larger than what above x = 0.58.
