/Si substrates by using a chemical solution deposition method. The thin films were phasepure with perovskite structure
no secondary phase was observed. Meanwhile
they were smooth
density and crack-free with small grain size of about 17 nm. Good electrical properties were observed in the films annealed at 700 ℃ for 1 h. The dielectric constant and the dissipation factor (at 1 kHz) were 265 and 5 %
respectively. Driven by a electric field of 500 kV/cm
PBT showed 2 Pr of and Ec of 110 kV/cm. These suggested that PBT had potentials in applications of ferroelectric devices.
