摘要:

单壁碳纳米管(SWNTs)的电子拉曼散射(ERS)特征可以揭示关于其电子结构的丰富信息,但以前被认为只出现在金属(M-)而不是半导体(S-)SWNTs中。我们报告的ERS功能的实验观测精度为1毫电子伏的悬浮S-SWNTs,其过程是通过可用的高能电子空穴对完成。ERS的功能,可以促进进一步系统的研究单壁碳纳米管的性质,金属和半导体,具有明确的手性。

英文摘要:

The electronic Raman scattering (ERS) features of single-walled carbon nanotubes (SWNTs) can reveal a wealth of information about their electronic structures, but have previously been thought to appear exclusively in metallic (M-) but not in semiconducting (S-) SWNTs. We report the experimental observation of the ERS features with an accuracy of 1 meV in suspended S-SWNTs, the processes of which are accomplished via the available high-energy electron-hole pairs. The ERS features can facilitate further systematic studies on the properties of SWNT, both metallic and semiconducting, with defined chirality.
