Abstract
The perovskite LaNiO3 (LNO) and Pb(Zr0.52Ti0.48)O3 (PZT) thin films were successfully prepared using metal-organic decomposition (MOD) process. Perovskite LNO phase can be obtained at temperature as low as 600°C (30 s) in rapid thermal annealing (RTA) process. However, additional furnace annealing (FA) at 650°C (60 min) is needed in order to lower the electrical resistivity of the LNO films to ρ ≤ 30 mΩ cm. Pure perovskite PZT films can easily be obtained by either RTA or FA process. Furnace post-annealing process (650°C, 60 min) results in a PZT film possessing significantly better ferroelectric properties than the RTA process (650°C, 60 s). The best properties obtained are remanent polarization Pr = 11.8 μC/cm2, coercive force Ec = 76.0 μC/cm2 and leakage current density JL ≤ 3 × 10-6 A/cm2 (for applied field ≤ 200 kV/cm). Using LNO films as buffer layer does not increase the ferroelectric properties of PZT films, but significantly improves fatigue behavior.
