Abstract :
Effects of (Nd, Cu) co-doping on the structural, electrical and ferroelectric properties of BiFeO3 polycrystalline thin film have been studied. Pure and co-doped thin films were prepared on Pt(111)/Ti/SiO2/Si(100) substrates by using a chemical solution deposition method. Significant improvements in the electrical and the ferroelectric properties were observed for the co-doped thin film. The remnant polarization (2Pr) and the coercive field (2Ec) of the co-doped thin film were 106 μC/cm2 and 1032 kV/cm at an applied electric field of 1000 kV/cm, respectively. The improved properties of the co-doped thin film could be attributed to stabilized perovskite structures, reduced oxygen vacancies and modified microstructures.
