Definition

Metal nanorods of a few micron length and a much smaller diameter feature strong plasmonic resonances in the infrared region and therefore act rather similar to radio antennas, but the spectral shape of such resonances is related to the conductivity of the nanoantenna material. In the scientific literature, analytic approaches exist which explain the relationship between the electronic conductivity and the resonance spectrum that is due to plasmon polaritons as mixed excitations from free electrons and photons.

Introduction

Metal nanowires are produced, for example, by electron-beam lithography (EBL), electrochemical, and wet chemical methods [1]. Usually they are inspected by scanning electron microscopy (SEM) or atomic force microscopy (AFM) in order to get geometric information; see Fig. 1. But, neither SEM nor AFM can deliver conductivity information of a nanoobject. Electrical...
