摘要:(Na0.5 Bi0.5) 0.87 Pb0.13 Ti O3 thin films have been prepared on PtTiSi O2 Si and Bi2 Ti2 O7 Si substrates using a metal organic decomposition method. The electrical measurements were conducted on metal-ferroelectric-metal or metal-ferroelectric-insulator-semiconductor capacitors. As Bi2 Ti2 O7 is an effective diffusion barrier, the leakage current and memory properties of (Na0.5 Bi0.5) 0.87 Pb0.13 Ti O3 Bi2 Ti2 O7 Si are relatively improved. The polarization-electric field and capacitance-voltage measurements of (Na0.5 Bi0.5) 0.87 Pb0.13 Ti O3 on Pt show good ferroelectric properties. The three phase transitions in (Na0.5 Bi0.5) 0.87 Pb0.13 Ti O3 can be recognized by the change of capacitance with temperature. © 2007 American Institute of Physics.
