摘要

Optical properties of high purity metallic and semiconducting single-wall carbon nanotubes (SWCNTs) were investigated from far infrared to ultraviolet by optical absorption spectroscopy. It was found that the metallic SWCNT thin film has larger infrared absorption intensity than the semiconducting one. Furthermore, little changes in the optical absorption spectrum and the DC sheet resistance against molecular physisorptions were revealed in the metallic SWCNTs thin film. The stability of the metallic SWCNTs results from their constant electronic density of state near the Fermi level. On the other hand, the existence of semiconducting SWCNTs in the films makes their infrared absorption intensity and the sheet resistance more sensitive to the adsorption of molecules mainly due to carrier doping.
