Figure 7

(a) Log-log plots of complex impedance (Z′ vs Z″) at different temperatures, (b) equivalent circuit based on the brick-layer model for the impedance spectra, (c) Arrhenius plots of the dc conductivities for grain and grain boundary obtained from the fitting results of equivalent circuit above 303 K.
