摘要: The interface between a PZT film and an Si(100) substrate was controlled by using heteroepitaxial YSZ buffer layer. A 10 nm thick layer able to prevent the from reacting with Si at temperature of 650°C produced highly c-axis-oriented perovskite film. polarization-voltage hysteresis measurement showed that PZT/YSZ/Si structure had ferroelectric properties although leakage current relatively large. From results capacitance-voltage current-voltage characteristics, it speculated this crystalline defects or carrier traps which generated large absorption short relaxation time constants.
