摘要：

MnO-modified Bi1.05FeO3 (BFO) thin films were fabricated on Pt(111)/Ti/SiO2/Si(100) substrates by using a pulsed laser deposition technique. The temperature-dependent ferroelectric and leakage current properties were investigated for 5% or 10% MnO-modified BFO thin films. The 5% MnO-modified BFO thin film exhibited a large remnant polarization and a low leakage current under a high electric field and in high temperature ranges. On the other hand, 10% MnO-modified BFO thin film showed a leaky ferroelectric nature at elevated temperatures with a sharp increase in the leakage current, due to the high density of defects.
