Abstract
Pb(Fe1/2Ta1/2)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 diffra ction and their micro structures were observed by transmission electro n 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 obtai ned at annealing temperatures between 680 degrees C and 730 degrees C.
