摘要：
0.94Na(0.5)Bi(0.5)TiO(3)-0.06BaTiO(3) (NBT-6BT) and (0.94 - x) Na0.5Bi0.5TiO3-0.06BaTiO(3)-xBiFeO(3) (NBT-6BT-xBFO, x = 0.03, 0.05 and 0.08) thin films were deposited on Pt/Ti/SiO2/Si substrates by a sol-gel process. Relative permittivity and remnant polarization were maximized at 5 % BFO substitution. Compared with 0.94NBT-0.06BT, the leakage current density of 0.89NBT-0.06BT-0.05BFO at 600 kV/cm is reduced by one order of magnitude. Enhanced ferroelectricity was also achieved in 0.89NBT-0.06BT-0.05BFO, the remnant polarization (2P(r)) values of 0.89NBT-0.06BT-0.05BFO and 0.94NBT-0.06BT are 46 and 24 mu C/cm(2).
