通过第一性原理计算，我们发现可以通过调节单壁碳纳米管中有机和有机金属分子的电子亲和势或电离势来实现p型和n型掺杂的微调。这种新型的基于单壁碳纳米管的材料由于其空气稳定性、合成简单以及丰富的有机和有机金属分子，为分子电子学提供了巨大的希望。
By using first principles calculations, we show that fine tuning of both p- and n-type doping can be realized on single-wall carbon nanotubes (SWNTs) by tuning the electron affinity or ionization potential of the organic and organometallic molecules encapsulated inside SWNTs. This novel type of SWNT-based material offers great promise for molecular electronics because of its air stability, synthetic simplicity and the abundance of organic and organometallic molecules.
