双壁碳纳米管（DWNT）由两个同轴的碳纳米管组成，是一种理想的化学和物理应用结构。因此，深入研究双壁碳纳米管的电输运与手性结构之间的一一对应关系具有重要意义。在这里，手性相关的输运性质的DWNTs已被系统地研究原位的场效应晶体管，通过建设DWNT为基础的场效应晶体管到透射电子显微镜。通过对双壁碳纳米管的研究，发现其输运特性与手性指数直接相关，并实现了对内管的原位探测。
Double-walled carbon nanotubes (DWNT), consisting of two coaxial tubes, is an ideal structure for chemical and physical applications. It is of essential importance to probe the one-to-one relationship between electrical transport and chiral structure of DWNTs. Here, the chirality-dependent transport properties of DWNTs have been systematically investigated in situ on their field-effect transistors, through building DWNT-based field-effect transistors into a transmission electron microscope. The transport characteristics of DWNTs can be directly correlated with their chiral indices, and the probe of inner tubes has also been achieved in situ.
