Dielectric behavior and AC conductivity mechanism of ZnCo2O4 ceramic nanoparticles as a function of frequency and temperature

In the present study, ZnCo2O4 nanoparticles were synthesized using the sol–gel method. Structural and morphological properties of the sample were analyzed using X-ray diffraction and scanning electron microscope. Cell volume, lattice parameter, dislocation density, and microstrain were calculated using the Debye Scherrer and Williamson Hall method. The temperature and frequency dependence of AC conductivity and dielectric properties of ZnCo2O4...
