Non‐Drude terahertz conductivity in nanomaterials: overview and applications to nanosilicon and nanogold

It is shown that a series sequence of transport involving grains and grain boundaries produces non-Drude THz conductivity in nanomaterials. The present model represents a different point of view than the well accepted Drude-Smith model. In this paper we review and describe how the complex conductivity is calculated and the real and imaginary parts of THz conductivity are obtained. We use two examples: nanoporous Si and nanogold (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
