Abstract

A crystalline (Na_0.5K_0.5)NbO₃ (NKN) phase was formed for a film grown at 600°C, but a K_5.75Nb _10.85O₃₀ (KN) second phase was also observed in this film. Formation of the KN phase was due to the evaporation of Na₂O. A homogeneous NKN phase was developed in the film grown at 300°C and annealed at 800°C under a Na₂O atmosphere. This film exhibited the following good electric and dielectric properties: a high dielectric constant of 237.4 with a dissipation factor of 0.93% at 100 kHz, a low leakage current density of 1.0 × 10^-8 A/cm² at 0.1 MV/cm ², and the high P_r and d₃₃ values of 21.1 μC/cm² and 64.5 pm/V, respectively.
