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.

该项目致力于为剑桥大学高分子材料实验室(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。利用时域光谱学(TDS)和光泵太赫兹探测光谱学(OPTPS)电荷载流子寿命，可以深入了解电荷载流子动力学和相当于交流电导率的量。希望通过对OPTPS结果的检查，可以找到每种纺织品中存在的半导体与金属纳米管的特征比例。
