PbTiO3 thin films were deposited by thermal decomposition of organometallic compounds and their electrical properties were studied. The dielectric constant of these films was estimated to be about 200. D–E hysteresis loops were observed in the films deposited on Pt plates. Remanent polarization and coersive force were about 37µC/cm2 and 130 kV/cm, respectively. Measured pyroelectric coefficient (dPr/dT) after applying a field of 150 kV/cm was 1×10-8 C·cm-2·K-1.
