Notes:
Thin films of a bismuth-based layer-structured perovskite compound with a number of oxygen octahedron along the c axis between Bi–O layers of three, CaBi3Ti3O12−δ, were prepared using a mixture solution of complex alkoxides. The films crystallized below 550 °C. The crystal structure and surface morphology of these films changed between 600 and 650 °C. The 650 °C-annealed thin film consisted of well-developed grains and exhibited polarization–electric hysteresis loops. The remanent polarization and coercive electric field were 8.5 μC/cm2 and 124 kV/cm, respectively, at 7 V. The dielectric constant and loss factor were about 250 and 0.048, respectively, at 100 kHz. © 2001 American Institute of Physics.
