| 1 | Semiconducting single-walled carbon nanotubes synthesized by S-doping显示文摘An approach was presented for synthesis of semiconducting single-walled carbon nanotubes(SWNTs) by sulfur(S) doping with the method of graphite arc discharge. Raman spectroscopy, UV-vis-NIR absorption spectroscopy and electronic properties measurements indicated the semconducting properties of the SWNTs samples. Simulant calculation indicated that S doping could induce convertion of metallic SWNTs into semiconducting ones. This strategy may pave a way for the direct synthesis of pure semiconducting SWNTs. | Z.J.Li L.Wang Y.J.Su P.Liu Y.F.Zhang | 2009 | Nano-Micro Letters2009，1，1： | 5 |
