基于C-60富勒烯豆荚的场效应晶体管的输运特性进行了研究，我们的研究结果表明，单壁碳纳米管（SWNTs）的输运特性是高度敏感的封装富勒烯由于电荷转移效应。在光照条件下，C-60豆荚中的光诱导电子转移特性，这是观察到的空单壁碳纳米管不同。peapod器件对光的响应特性反映在阈值电压向负值的偏移中，表明电子掺杂过程。在去除光之后，光响应是完全可恢复的，表明转移的电子完全恢复。(C)2008年美国物理学会。
The transport properties of field-effect transistors based on C-60 fullerene peapods have been investigated and our findings indicate that the transport characteristics of single-walled carbon nanotubes (SWNTs) are highly sensitive to the encapsulated fullerenes due to the charge-transfer effect. Under light illumination, the photoinduced electron transfer characteristics are found in C-60 peapods, which is different from those observed for empty SWNTs. The response characteristic of peapod devices to light is reflected in a shift of threshold voltage toward negative values, indicating an electron-doping process. After removing light the photoresponse is fully recoverable, indicating complete restoration of transferred electrons. (C) 2008 American Institute of Physics.
