Electrical transport properties of C60 and C59N encapsulated single-walled carbon nanotubes (SWNTs) are investigated by fabricating them as the channels of field effect transistor (FET) devices at room temperature. Their measurements indicate that C60@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 can modify the electronic structure of SWNTs.
通过在室温下将C60和C59N封装的单壁碳纳米管（SWNTs）制作成场效应晶体管（FET）器件的沟道，研究了它们的电输运特性。测量结果表明，与原始单壁碳纳米管相比，C60@SWNTs表现出增强的p型特性，而C59N@SWNTs表现出n型行为。豆荚状纳米管的这种新颖输运特性可以通过电荷转移效应来解释，该效应可以改变单壁碳纳米管的电子结构。
