Abstract
The SrBi2Ta2O9 (SBT) thin film was prepared by the pulsed laser deposition (PLD) combined with annealing technique. The SBT thin film showed a well-saturated hysteresis loop with Pr of 8.4 μC/cm2 and Ec of 57 kV/cm at 5 V. No fatigue was observed up to 1010 switching cycles. The I-V characteristic showed two peaks at the coercive voltage. It had a 560 pF capacitance and a static dielectric constant of 600 at zero applied voltage from the I-V characteristic. Leakage current measurements showed about 3 × 10-8 A/cm2 and the dc breakdown field was 250 kV/cm.
