Abstract
A method for modulation of yield and semiconducting (sc)-purity of single-walled carbon nanotubes (SWCNTs) in a conjugated polymer extraction (CPE) process, the method comprising addition of an n-type dopant or a p-type dopant to the CPE process, wherein: the n-type dopant has a reduction potential of between −4.2 eV and −3.0 eV; and the p-type dopant has a reduction potential of between −6.0 eV and −4.5 eV.
