The SNNO- nanosheets were deposited on a Pt/Ti/SiO2/Si substrate at room temperature by the electrophoretic method. Annealing was conducted at various temperatures to remove organic defects in the SNNO film. A crystalline SNNO phase without organic defects was formed in the film annealed at 500 degrees C. However, a SrNb2O6 secondary phase was formed in the films annealed above 600 degrees C, probably due to the evaporation of Na2O. The SNNO thin film annealed at 500 degrees C showed a dielectric constant of 74 at 1.0 MHz with a dielectric loss of 2.2%. This film also exhibited a low leakage current density of 9.0 x 10(-8) A/cm(2) at 0.6 MV/cm with a high breakdown electric field of 0.72 MV/cm. (C) 2017 Elsevier Ltd. All rights reserved.
