Carbon nanotubes (CNTs) have captured the interest of scientist due to their large aspect ratios, remarkable optical, electrical and mechanical properties. There has been great community effort to realize these properties in a macroscopic material. Recently, breakthroughs have allowed us to produce wafer-scale, highly aligned CNT films that preserve the excellent nanoscale properties such as high electron mobility. In order to further increase electron mobility, chemical doping is used. In this study, we use terahertz spectroscopy in order to investigate the effectiveness of 6 different dopants and their stability over time.
