Characteristics of yttrium substituted sodium bismuth titanate thin films

Ferroelectric and piezoelectric properties of lead-free BaTiO3 doped Bi0.5Na0.5TiO3 thin films from metal-organic solution deposition

“…2. These patterns indicate the coexistence of a perovskite phase and a secondary pyrochlore Bi 2 Ti 2 O 7 phase formed by post annealing the films at 600°C [31,32]. However, the pyrochlore phase is practically eliminated at higher temperatures and the dominant phase at 650°C is the perovskite.…”

Effects of Zr doping content on microstructure, ferroelectric and dielectric properties of Na0.5Bi0.5TiO3 thin film

“…During the past decades, Na 0.5 Bi 0.5 TiO 3 (NBT) shows the potential in replacing lead-based compounds due to its excellent ferroelectric properties with a relatively large remanent polarization (P r ) of 38 μC/cm 2 and high Curie temperature (T c ) of 320 1C at room temperature [1]. Nevertheless, for NBT, especially in the form of thin film, its inherent electrical properties are difficult to be measured due to some commonly encountered difficulties, i.e.…”

Microstructure and electrical properties of Na0.5Bi0.5(Ti0.98Zr0.02)O3 thin film deposited on indium tin oxide/glass substrate

“…The NBTZr film matches well with the rhombohedral perovskite structure and exhibits polycrystalline nature without preferential orientation. No detectable impurity phases can be observed although secondary phases can be formed sometimes along with the peroskite phase due to the volatilization of Na + or Bi 3+ [10,11]. This is closely related to the addition of PEG600, which favors the formation of perovskite structure, as investigated in our previous work [7].…”
