Abstract :
The exhibiting electrical properties of ferroelectric thin films usually are influenced by the electrode materials. In this paper, platinum (Pt), gold (Au) are selected as the top electrode materials for 0.6(Bi0.85La0.15)FeO3-0.4PbTiO3 (BLFO-PT) thin films. The Pt and Au electrodes were prepared by sputtering technique and annealed at 350degC. The effect of the top electrode materials is analyzed. The dielectric constants and loss factors of these thin films were checked under different temperatures. It shows that not only the Curie temperature of the films but also the dielectric behavior during the heating and cooling procedure carried out in the films is influenced by top electrode.
