摘要：

In this paper, we report on the optical and electrical properties of single-walled (SWNT) and multi-walled (MWNT) carbon nanotube thin-films investigated by terahertz time-domain spectroscopy. Our study focuses on the absorption and dispersion properties of the single-walled and multi-walled carbon nanotubes in frequency range of 0.1-2 THz. The results show that the single-walled carbon nanotubes thin-films have the great frequency-dependent of the power absorption coefficient, the index of the refraction and conductivity compared to the multi-walled carbon nanotubes thin-films because more mobile carries of carbon nano-structure as well as effective of carbon nanotubes length and diameter.
