摘要：
The azafullerene C59N is synthesized by a nitrogen plasma irradiation method, which has been confirmed by the analysis of mass spectroscopy. The encapsulation of C59N inside single-walled carbon nanotubes (SWNTs) is practiced via a vapor diffusion method. Electrical transport properties Of C-60 and C59N encapsulated SWNTs are investigated by fabricating them as the channels of FET devices at room temperature. It is found that the electrical transport properties Of C-60@SWNTs exhibit the enhanced p-type characteristics compared with the case of pristine SWNTs, whereas C59N@SWNTs show the n-type behavior. The novel transport properties of peapods can be explained by the charge-transfer effect, which call modify the electronic structure of SWNTs.
