Infrared conductivity measurement of nanostructures — •Annemarie Pucci1,2,3, Christian Huck1, Jochen Vogt1, Fabian Hötzel1, Akemi Tamanai1,2, Jens Trollmann1,2, and Tobias Glaser1,21Kirchhoff Institute for Physics (KIP), Heidelberg University, Heidelberg, GERMANY — 2InnovationLab GmbH, Heidelberg, GERMANY — 3Centre for Advanced Materials (CAM), Heidelberg University, Heidelberg, GERMANY

Nanostructures from materials with free charge carriers, as for example gold, ITO, and doped semiconductors, may show plasmonic absorption in the infrared, which allows conductivity measurement without electrical contacts. The electronic relaxation rate as a measure of crystalline quality can be separately derived from the spectra, even for nanowires.
