Özet

Terahertz: spectroscopy is used to definitively distinguish between two multi-walled carbon nanotubes (see figure), which have commercial applications in a number of advanced materials. Other techniques do not provide a sensitive discrimination of the measured properties. This observation is rationalized by considering the dielectric nature of the materials and the relationship of this to their structural differences.
