Method of selectively eliminating metallic carbon nanotubes, semiconducting carbon nanotubes and preparation method thereof using the same

摘要

Metallic carbon nanotubes (“CNTs”) may be selectively eliminated and semiconducting CNTs may be prepared using light-irradiation. The light provided by the light-irradiation may have a wavelength of about 180 nm to about 11 μm. Further, the light may have an intensity of about 30 mW/cm² to about 300 mW/cm². The light-irradiation may be simple and controllable, and may not require any special instruments except a light source.
