Dielectric Properties of Au-BaTiO3 Nanocomposite Films Prepared by Sol-Gel Method

doi:10.15541/jim20140271

Abstract

Abstract:

Au-BaTiO₃ nanocomposite thin films were prepared on Pt/Ti/SiO₂/Si substrates by a Sol-Gel method and their crystal structure, microstructure and dielectric properties were investigated. Au nanoparticles with diameter of 5-22 nm are distributed in the BaTiO₃matrix. Au concentration has great effects on the surface morphology and dielectric properties of the composite thin films, and the optimal concentration of Au is about 5mol%. The composite thin films have crystallized into the perovskite phase after annealing at 550℃, and their dielectric constant is equivalent with that of the pure BaTiO₃ thin films annealed at 700℃. The enhanced crystallization of Au-BaTiO₃ composite film is attributed to the addition of Au nanoparticles, which can promote the decomposition of the intermediate phase and induce a heterogeneous nucleation of the perovskite phase. Thus, the annealing temperature of the composite films is drastically reduced and their dielectric properties are improved significantly with the addition of Au nanoparticles.
