|Abstract:||To understanding the combined effects of bilayer structure and ion substitutions on electrical behavior of BiFeO3 thin films, the Bi0.90La0.10Fe0.90Zn0.10O 3/Bi0.90La0.10Fe0.90Sn 0.10O3 bilayers with different thickness ratios were fabricated on SrRuO3/Pt/TiO2/SiO2/Si(100) substrates by radio frequency sputtering. Their dielectric constant increases and the fatigue endurance becomes better with increasing Bi 0.90La0.10Fe0.90Zn0.10O3 thickness ratios. The bilayer with the thickness ratio of 210: 90 exhibits a high remanent polarization, and a better fatigue behavior is induced by higher driving electric fields and frequencies. © 2011 American Institute of Physics.|
