Popis: Pb(Fe 1 2 Ta 1 2 ) O 3 (PFT) thin films with the perovskite structure have been prepared successfully on Si(III) substrates by a sol-gel process. The crystallinity of the thin films was characterized by X-ray diffraction and their micro structures were observed by transmission electron microscopy (TEM). It was found that the perovskite phase could only be formed with an excess lead content over stoichiometric composition and primary perovskite phase with a strong (110) orientation was obtained at annealing temperatures between 680 °C and 730 °C.
