Hopping conduction in solids
Web10 apr. 2024 · The electrical conductivity (mixed conduction) is found to be a function of frequency as well as temperature. In the low-frequency range, it shows a flat conductivity owing to the diffusional motion of Na + ions, whereas at high frequency, the conductivity shows dispersion.
