| 摘 要： | 本文利用脉冲激光沉积技术在(LaAlO3)0.3(Sr2AlTaO6)0.7(001)衬底上生长了BiFe1-xMnxO3(x=0～5%)外延薄膜,研究了Mn掺杂对BiFeO3(BFO)薄膜结构、铁电特性和漏电流的影响.XRD和SEM结果表明薄膜具有良好的结晶质量.漏电流测量显示Mn掺杂有效地减小了BFO薄膜的漏电流密度,因而在室温下5%Mn掺杂的BFO薄膜能够获得饱和的电滞回线.XPS分析证明,Mn掺杂改善BFO薄膜性能的可能原因在于其极大地减少了BFO薄膜中的Fe2+离子.

| Abstract: | Mn-doped BiFeO3 films have been grown on(LaAlO3)0.3(Sr2AlTaO6)0.7(001)substrates by the pulsed laser deposition method,and the effects of Mn-doping on their leakage and ferroelectric properties were investigated.The current density versus electric field curves measured from the Mn-doped and undoped BFO epitaxial films indicate that the Mn-doping can effectively suppress the leakage current.As a result,we got well-saturated polarization-electric field hysteresis-loops in 5% Mn-doped BFO film at room temperat... |
