Electrical and energy storage properties of nickel substituted barium bismuth niobate nano-ceramics prepared by chemical route

Inhibition of Oxygen Vacancy Derived from Donor Doping in Relaxor Ferroelectric Films for Improving Dielectric Energy Storage

“…Figure a shows the XRD patterns of the SrBi 4 LaMg 0.5– x Ti 4.5 O 18 : x Fe films. It is well known that the highest diffraction peak of the polycrystalline Aurivillius phase layered perovskite material is (1 1 2 m +1), where m is the number of layers of the layered perovskite . From Figure a, it can be seen that the (1 1 11) diffraction peak is the highest diffraction peak, i.e., m = 5, indicating that the SrBi 4 LaMg 0.5– x Ti 4.5 O 18 : x Fe film is a five-layer perovskite structure.…”

Influences of crystallization temperature on the structure, dielectric, and energy storage characteristics of KBaSrNb5O15‐based glass–ceramics

“…In order to further study the relationship between interface polarization and BDS, the complex impedance as a function of the frequency of the KBSNB glass–ceramics at various temperatures was measured, and corresponding activation energy ( E a ) is calculated, as shown in Figure 8. From Figure 8A–D, there is only a peak at each temperature for all samples, and the crest value decreases with the temperature rising, which indicates that the conductivity rises as the temperature rises 36 . Figure 8E shows the relationship of $$\ln \tau $$ and 1000/ T , and the corresponding E a can be calculated by formula (4).…”

The variation of both E a and BDS with the crystallization temperature for KBSNB glass-ceramics is displayed in Figure 8F.…”
