摘要
(Pb,La)TiO3 (PLT) and (Pb,La)(Zr,Ti)O-3 (PLZT) thin films were successfully grown by MOCVD, using (C2H5)(3)PbOCH2C(CH3)(3), La(dpm)(3), Zr(O-t-C4H9)(4) and Ti(O-i-C3H7)(4) as precursors. The PLT and PLZT thin films showed good dielectric and ferroelectric properties. PLZT films showed better fatigue properties than PZT films. Large area growth of PLZT thin films on a 6 inch silicon wafer was carried out and uniform PLZT films with a variation in film thickness of +/-1.5% could be obtained. The case of La(i-C3H7C5H4)(3) as a new La precursor for growing PLT and PLZT will be discussed.
