Structural and Electrical Properties of Chemical Solution Deposited 0.7BiFeO3-0.3CaTiO3 Solid Solution Thin Film J. W. Kim, C. M. Raghavan, J. Y. Choi, S. S. Kim* Department of Physics, Changwon National University, Changwon, Gyeongnam 641-773, Korea ∗sskim@changwon.ac.kr Keywords: BiFeO3, CaTiO3, Solid solution system, Chemical solution deposition, Ferroelectric properties, Thin film A 0.7BiFeO3-0.3CaTiO3 (7B3C) solid solution thin film was prepared on a Pt(111)/Ti/SiO2/Si(100) substrate by using a chemical solution deposition method. The microstructure and the surface morphology of the 7B3C solid solution thin film were investigated by an X-ray diffraction pattern, a Raman scattering spectrum and a SEM analysis. For electrical measurements, the upper platinum dot electrodes with areas of 1.54¢®¢¯10-4 cm2 were deposited by an ion sputter through a shadow mask. The improved electrical properties were observed in the 7B3C solid solution thin film compared to the pure BiFeO3 thin film.
