Infrared conductivity measurement of nanostructures — •Annemarie Pucci^1,2,3, Christian Huck¹, Jochen Vogt¹, Fabian Hötzel¹, Akemi Tamanai^1,2, Jens Trollmann^1,2, and Tobias Glaser^1,2 — ¹Kirchhoff 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.
