- Abstract
In this paper, the BaTiO/Ni composite films of 10 μm were fabricated by Aerosol deposition. We investigate the dielectric behavior of BaTiO/Ni composite films with various Ni contents. The BaTiO/Ni composite film with Ni content of 9.1 vol% has high dielectric constant at 1 kHz (476) due to the percolation effect. This high dielectric constant was attributed to the microcapacitor structures and Maxwell-Wagner polarization. Although the BaTiO/Ni composite film was fabricated at room temperature, it had a high dielectric constant of 8 times higher than that of raw BaTiO film, and showed a very low leakage current. Therefore, BaTiO/Ni composite films fabricated by Aerosol deposition can potentially be used as embedded capacitors.
