Abstract
Ferroelectric PbTiO3 epitaxial thin films have been formed on a base electrode of Pt(100)/MgO(100) using ArF excimer laser ablation. The x-ray diffraction patterns of these films show c-axis orientation with a rocking angle of 0.5 when the film is cooled faster than 75 °C/min after the deposition. The films exhibit clear and large ferroelectric hysteresis loops. The dielectric constant of the films is 130 and remnant polarization is 80 μC/cm2. The values are almost the same as those theoretically predicted. The pyroelectric coefficient of these films is 1000–1500 V/W at 10 Hz, even without poling treatment.
