摘要
Hetero-epitaxially grown perovskite (100) three-axis-oriented (Ba0.7Sr0.3)TiO3 thin films were prepared on (100) platinum coated (100) magnesium oxide (MgO) single crystal substrate by the chemical solution deposition method using a solution derived from Ba(CH3COO)(2), Sr(CH3COO)(2), and Ti(O-i-C3H7)(4). The growth of the film was found to depend on the heat treatment condition. A (Ba,Sr)TiO3 thin film heat treated at 800 degrees C was found to be three-axis-oriented by TEM. The film exhibited a (100) three-axis-orientation that followed the (100) orientation of the Pt substrate, as observed from an X-ray pole figure measurement and SAED patterns. The C-V measurement and the temperature dependence of the dielectric constant were performed to reveal the electrical properties of the films.
