Electrical and thermal transport properties of Ni1-xCexO nanostructures

Electrical and thermal transport properties of Ni1-xCexO nanostructures

In this report, we discussed the structural, electric conduction (DC and AC) mechanisms and thermal properties such as specific heat (CP) and change in enthalpy (ΔH) of Ni1-xCexO (x = 0.00, 0.01, 0.03 and 0.05) nanostructures synthesized by the sol-gel method which have been explored through LCR and...

Zusammenfassung:In this report, we discussed the structural, electric conduction (DC and AC) mechanisms and thermal properties such as specific heat (CP) and change in enthalpy (ΔH) of Ni1-xCexO (x = 0.00, 0.01, 0.03 and 0.05) nanostructures synthesized by the sol-gel method which have been explored through LCR and differential thermal analysis (DTA) measurements. The dielectric relaxation in this system has also been discussed as a function of both frequency (75 kHz–1 MHz) and temperature (30 °C to 300 °C). In the light of several theoretical models, the AC conductivity has been analyzed using a power law σac∝ωs (s
