Abstract

The terahertz optical constants of two commercial multi-walled carbon nanotubes (MWCNTs) are measured and analysed using terahertz time-domain-spectroscopy. The optical constants have been used to fit models of their electronic properties in order to understand the observed differences and suitability for use in various applications.
