Notes:
Polycrystalline SrBi2Ta2O9 ferroelectric thin films were grown on Pt/Ti/SiO2/Si substrates using pulsed-laser deposition. By adjusting the laser fluence, we could successfully control remnant polarization of the films. In a narrow fluence range of 1.0–1.5 J/cm2, films with large remnant polarizations (as high as 18.7 μC/cm2) could be obtained. The choice of an optimal laser fluence was found to be very important to control electrical properties of the films. From electron-probe microanalysis, it was demonstrated that the Bi content is closely related with the remnant polarization. © 1999 American Institute of Physics.
