Abstract
High quality SrBi2Ta2O9 thin films on Pt/Ti/SiO2/Si substrates were obtained using pulsed laser deposition combined with annealing at 700°C in oxygen. The high diffraction peak of(008) and (115) was characterized by X-ray diffractometer. Good ferroelectric properties were obtained from the thin films; the remnant polarization and coercive field were about 10 μC/cm2 and 57 kV/cm, respectively. No fatigue was observed at up to 1010 switching cycles. Leakage current and the dc breakdown field measurement were about 4 × 10-8 A/cm2 at 5 V and 250 kV/cm, respectively.
