Abstract: It is known from the terahertz (THz) spectroscopies that deviation from the Drude law for free carriers is dramatic in most electronically conductive nanomaterials. It is suggested that among a variety of theoretical formalisms, a model of series sequence of transport involving grains and grain boundaries provides a reasonable explanation of Lorentz-type resonance (non-Drude behavior) in nanomaterials. Of particular interest is why do free carriers behave as a Lorentz-type resonance.
