Abstract: The three different doped (Na, K and Mg) Na0.5Bi0.5TiO3 compounds were prepared. The grain conductivity of the doped Na0.5Bi0.5TiO3 compounds shows: Na-doping > K-doping > Mg-doping. Using the dielectric relaxation spectroscopy, the relaxation parameters can be obtained: ENa = 0.61 eV, EK = 0.64 eV…

Abstract: Ag0.91Sm0.03NbO3-modified Na0.5Bi0.5TiO3–BaTiO3 ceramics (0.94−x)Na0.5Bi0.5TiO3–0.06BaTiO3–x(Ag0.91Sm0.03)NbO3 (x = 0, 0.03, 0.06, and 0.09) were prepared by solid-state reaction method. The structural, dielectric, and energy storage properties of the ceramics were systematically studied. Our results indicate that all ceramics exhibit…

Abstract: Abstract Fe-doped Na0.5Bi0.5TiO3 (NBTFe) thin films were prepared directly on indium tin oxide/glass substrates using a chemical solution deposition method combined with sequential layer annealing. The X-ray diffraction, scanning electron microscopy and insulating/ferroelectric/dielectric measurements were…

Modification of (Na0.5Bi0.5)0.95Ba0.05]0.98La0.02TiO3 ceramic with a proper amount of K0.5Na0.5NbO3 can effectively improve the temperature-stable of dielectric properties. A variation in dielectric constant is…
