Abstract :
We study the terahertz response of vertically aligned carbon nanotubes (VA-CNT) using THz time-domain spectroscopy, in order to determine optimal conditions for their use as THz-based gas sensors. The morphology of such films must be considered to reconcile the reflected signals and extract the complex conductivity spectra.
