Low Temperature Electrical Transport Study on Polymer/Carbon-Fiber Composites: Analysis beyond Mott’s Transition

Article Preview

Abstract:

The low temperature DC electrical conductivity of laminated conductive polymer composites with different concentrations of carbon fibers as a filler has been investigated. The electrical behavior below 105 K for all concentrations could be explained in terms of 3D Mott’s model that is the hopping conductivity can be considered as the dominating charge transport mechanism. From this model, the hopping distance, the density of state at Fermi level, and the decay constant for this material were determined.
