ABSTRACT

Lead zinc niobate (PZN)-added lead zirconate titanate (PZT) thick films with thickness of 5~10 μm were fabricated on silicon and sapphire substrates using aerosol deposition method. The contents of PZN were varied from 0 %, 20 % and to 40 %. The PZN-added PZT film showed poorer electrical properties than pure PZT film when the films were coated on silicon substrate and annealed at 700°C. On the other hand, the PZN-added PZT film showed higher remanent polarization and dielectric constant values than pure PZT film when the films were coated on sapphire and annealed at 900°C. The ferroelectric and dielectric characteristics of 20 % PZN-added PZT films annealed at 900°C were compared with the result values obtained from bulk ceramic specimen with same composition sintered at 1200°C. As annealing temperature increased, dielectric constant increased. These came from enhanced crystallization and grain growth by post heat treatment.
