A critical path approach for elucidating the temperature dependence of granular hopping conduction

Abstract

We revisit the classical problem of granular hopping conduction's temperature dependence, and offer a straightforward and simple explanation on a phenomenon that was widely observed over diverse material systems, but which has remained a puzzle in spite of the various efforts for its explanation.
