Abstract:

Highly oriented Bi4Ti3O12 thin films were prepared by Sol-Gel technique on SrTiO3(100) single crystal, using Bi(NO3)3.5H2O, Ti(OC4H9)4 and CH3COOH as raw materials. The c-axis orientation was about 96%. The effect of pH value of solution on quality of the thin films was studied.

Key words: Sol-Gel method, Bi4Ti3O12 oriented thin films, SrTiO3substrate
