Ultrafast terahertz spectroscopy of highly aligned carbon nanotube textiles

该项目关注的是对剑桥大学大分子材料实验室（MML）生产的碳纳米管（CNT）纺织品的基本电学特性带来新的见解。利用时域光谱（TDS）和光泵太赫兹探测光谱（OPTPS）的电荷载流子寿命，洞察电荷载流子的动力学和数量相当于交流电导率可以提取。希望通过检查OPTPS的结果，可以找到每种纺织品中存在的金属纳米管与金属纳米管的特征比率。

The project is concerned with bringing new insights with regard to the fundamental electrical properties of the carbon nanotube (CNT) textiles being produced by the University of Cambridge's Macromolecular Material Laboratory (MML). Utilising time-domain spectroscopy (TDS) and optical pump-terahertz probe spectroscopy (OPTPS) charge-carrier lifetimes, insights into the charge-carrier dynamics and quantities equivalent to ac conductivity can be extracted. It is hoped that through examination of the results from OPTPS, a characteristic ratio of the semiconducting-to-metallic nanotubes present in each textile can be found.
