(a) Impedance plane plots of CuO nanograins with increase in frequency from right to left. (b) Capacitances of the Gs and GBs as a function of temperatures.
Variation of the resistances as a function of inverse temperatures. (a) Solid lines are best fit to the adiabatic SPH model at higher temperatures and (b) MVRH model at lower temperatures.
(a) Variation of Z// vs frequency. Inset shows variations of Z//with frequency at higher temperatures, (b) variation of ɛ/ with frequency at different temperatures, and (c) variation of the grain boundary relaxation time as a function of inverse temperatures. Solid lines above 303 K are best fit to the adiabatic SPH model. Inset shows the best fitted results to the MVRH model at lower temperatures.
