In this Phase II effort, we will scale-up to commercial levels a proprietary technology for producing highly semiconducting enriched (99%) single-walled carbon nanotubes (SWNTs). The technology utilizes a technique, called density gradient ultracentrifugation (DGU), to separate as-grown SNWTs by their optoelectronic properties. If successful, our technology will enable the economic production of very large quantities of SWNTs that are uniformly semiconducting.
