A/B位离子掺杂BiFeO3纳米薄膜的微结构与铁电性能
Structure and Ferroelectric Properties of BiFeO3 Nano-Crystalline Film Substituted at A/B Site
摘要
Abstract
The nano-crystalline ferroelectric films composed of BiFe0.95Mn0.05O3 and Bi0.9Nd0.1FeO3 were fabricated on the fluorine-doped tin oxide/glass substrates via the simple and cost-effective chemical solution deposition method combined with spin-coating and the subsequent layer-by-layer annealing technique.Microstructures and ferroelectric properties of the samples were investigated.Results show that either BiFe0.95Mn0.05O3 or Bi0.9Nd0.1FeO3 film has a single polycrystalline perovskite phase structure with fine and homogeneous grains and smooth surface in addition to a compact and dense structure.Both film samples exhibited well-saturated polarization-electric field hysteresis loops.Especially,the BiFe0.95Mn0.05O3 film showed more preferential upward polarization orientation and superior ferroelectric properties than the Bi0.9Nd0.1FeO3 film,which was reflected by a high remanent polarization(Pr)of 60 μC·cm-2 and stable ferroelectric responses to frequency and temperature in the ranges of 1 to 50 kHz and 25 to 200℃in addition to retention capability of 1×103 seconds and fatigue endurance over 1×109 cycles.关键词
