碳纳米管因其一维的管状分子结构,表现出优异的力学、电学和光学等性质,在微纳光电子器件、生物医药、新能源材料等方面具有广阔的应用前景。碳纳米管特殊的性质来源于其结构。原子结构排列上的微小差异将导致碳纳米管光电性质的巨大区别。如:碳纳米管由于结构的不同可以是金属性的,也可以是半导体性的;每一种手性碳纳米管有一对左右螺旋对称的镜像体,表现出相反的旋光特性(被称作旋光异构体)等。宏量获取单一结构、均一性质的碳纳米管是研究其性质,推动其应用的关键。现有的碳纳米管生长技术或 Due to its one-dimensional tubular molecular structure, carbon nanotubes exhibit excellent mechanical, electrical and optical properties and have broad application prospects in micro-nano-optoelectronic devices, biomedicine and new energy materials. The special properties of carbon nanotubes come from their structure. A slight difference in the arrangement of atomic structures will result in a huge difference in the electro-optical properties of carbon nanotubes. For example, carbon nanotubes can be metallic or semiconducting because of their different structures. Each of the chiral carbon nanotubes has a pair of left and right spiral symmetric mirrors exhibiting opposite optical rotations (referred to as optical rotation Isomers) and the like. Macro-level access to a single structure, uniform nature of carbon nanotubes is to study the nature of the key to promote its application. Existing carbon nanotube growth techniques or
