Ni doping to enhance ferroelectric, energy-storage and dielectric properties of lead-free NBT ceramic thin film with low leakage current
Source abstract
Abstract
Abstract Electrical performances can be enhanced through Ni 2+ substitution in Na 0.5 Bi 0.5 TiO 3 (NBT) ceramic thin film. The microstructure, leakage, ferroelectric and energy-storage performances as well as dielectric properties of Ni 2+ -doped NBT were investigated and discussed. The perovskite structure can be maintained well in spite of various compositions. With the increase of Ni 2+ content, the average grain size deceases obviously. Compared with all the other samples, NBT with 3 mol% Ni 2+ substitution exhibits a remanent polarization ( P r ) of 16.5 μC/cm 2 , acceptable recoverable energy storage density of 14.8 J/cm 3 and energy storage efficiency of 49.0% as well as a high dielectric tunability of 21.7% as consequences of highly dense micrograph and reduced leakage current. These results indicate that appropriate Ni 2+ substitution for Ti 4+ in NBT film is a promising feasible way to solve the leakage problem and achieve desired ferroelectric, energy-storage and dielectric properties.
