Paper Abstract

4nm single-walled carbon nanotubes ( SWNTs ) of three possible structures were fabricated. The frequency-domain transmission spectrum of SWNTs was obtained by Fourier transform in terahertz time-domain spectroscopy (THz-TDS) system. By analyzing the spectrum, we can see that the absorption coefficient of SWNTs augments with an increase in the frequency. It increases slowly at low frequency, and almost be linear. But after 1.1THz, the absorption coefficient rises rapidly with the frequency. The result is generally corresponding with the theory Drude-Lorentz model combined with the Maxwell-Garnett model. But there is some difference at low frequency, further discuss is needed.
