Ultrafast terahertz spectroscopy of highly aligned carbon nanotube textiles

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.
