Popis: SrBi2Ta2O9 thin films were prepared by metalorganic chemical vapor deposition(MOCVD) from Bi(CH3)3 – Sr[Ta(O. C2H5)6]2,-O2 system. Bi(CH3)3 is liquid and take a higher vapor pressure and gas concentration stability than conventionally used Bi sources, Bi(C7H7)3 and Bi(C6H5)3. The single phase of SrBi2Ta2O9 film was successfully prepared at 670[ddot]C on (111)Pt/Ti/SiO2/Si substrate. Epitaxially grown SrBi2TaO9 with c-axis orientation was also deposited on (100)SrTiO3 substrates at low temperature of 640[ddot]C.
