| Abstract: | Lithium tantalite (LiTaO3) thin films have been fabricated by sol-gel technique and crystallized by RTA process. The effect of heating temperature on the structural properties of LiTaO3 is investigated. The thin films are characterized by means of X-ray diffraction, Raman spectroscopy and thermal analysis (DCA/DTA). After the optimization of the growth parameters of LiTaO3 prepared by sol-gel processing, the pyroelectric property of LiTaO3 thin films deposited on Si (1 0 0) substrates have been also investigated. |
