Abstract

It is known that deviation from the Drude law is dramatic in most electronically conductive nanomaterials. A brief review of this topic is given, and it is shown that a series sequence of transport involving grains and grain boundaries produces a type of Lorentz resonance (non-Drude behavior) in nanomaterials. The physical parameters deduced from this model are reasonably good.
