摘要：
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/cm(2), films with large remnant polarizations (as high as 18.7 mu C/cm(2)) 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. (C) 1999 American Institute of Physics. [S0003-6951(99)03234-9].
