Bi0.94Ce0.06Fe0.97Ti0.03O3 and Bi0.94Ce0.06Fe0.97Ti0.03O3/Bi3.15Nd0.85Ti3O12 double-layered thin films were fabricated via sol-gel process on Pt/Ti/SiO2/Si substrates. The influence of Bi3.15Nd0.85Ti3O12 buffer layer on microstructure and electrical properties of Bi0.94Ce0.06Fe0.97Ti0.03O3 thin films were investigated in detail. Well-saturated P-E hysteresis loops can be obtained in Bi0.94Ce0.06Fe0.97Ti0.03O3 films with Bi3.15Nd0.85Ti3O12 buffer. The remnant polarization (2Pr) of the double-layered thin films is 112 μC/cm2. The coercive field (2Ec) of double-layered films is 672 kV/cm, which is much lower than that of the Bi0.94Ce0.06Fe0.97Ti0.03O3 thin films. The leakage current density of Bi0.94Ce0.06Fe0.97Ti0.03O3/Bi3.15Nd0.85Ti3O12 double-layered thin films is 4.12×10-5 A/cm2.

The electrical properties need to be improved, although Aluminum doped ZnO thin films (ZnO: Al) have been successfully deposited on transparent TPT substrates by our group. In this paper, ZnO: Al film was deposited on TPT substrate with SiO2 buffer layer by RF magnetron sputtering. The obtained film had a hexagonal structure and highly (002) preferred orientation. Compared with ZAO film without buffer layer, the lattice constant distortion of the film with buffer layer was decreased and the compressive stress was decreased by 9.2%, reaching to 0.779GPa. The carrier concentration and hall mobility of the film with buffer layer were both increased; especially the carrier concentration was enhanced by two orders of magnitude, reaching to 2.65×10+20/cm3. The resistivity of ZAO film with SiO2 buffer layer was about 7.6×10-3 Ω·cm and the average transmittance was over 70% in the range of 450~900nm.
