SouthWest NanoTechnologies (SWeNT) Receives NIST Small Business Innovation Research (SBIR) Phase 1 Award to Produce Greater than 99% Semiconducting Single-Wall Carbon Nanotubes

Norman, OK | Posted on September 19th, 2014

SouthWest NanoTechnologies (SWeNT), a leading manufacturer of single-wall, few-wall and multi-wall carbon nanotube materials for composite, printed electronics, and energy storage applications has received an SBIR Phase 1 Award from the National Institute of Standards and Technology (NIST).

The Phase 1 and subsequent Phase 2 Award worth up to $390,000, will fund efforts for scalable and selective synthesis of >99% semiconducting enriched SWCNTs.

"Using SWeNTs patented CoMoCATŽ technology and NIST separation technology this effort will yield scalable, affordable and chirally-pure SWCNT electronics materials for the semiconductor industry.

Semiconducting SWCNTs will enable superior printed thin-film transistors with >gHz switching behavior, high carrier mobility, high drive current, and exceptional stability in the face of environmental stressors like sunlight, humidity, and temperature. Printed electronics analysts report devices such as displays, medical sensors, chemical sensors, solid-state infrared detectors, and flexible logic devices are rapidly migrating away from expensive photolithographic synthesis methods to less-costly, printing-based fabrication techniques.

SWCNTs typically include both semiconducting and conductive tubes mixed together in different ratios. SWeNT intends to further develop the technology invented at NIST for separating tubes by electronic type using simple aqueous chemistry. The goal is to isolate populations of SWCNTs that are ultra-enriched in semiconducting tubes, without the need for high-speed centrifugation or covalent chemistry of any kind.

Arthur explains that, "Semiconducting SWCNTs may help chip developers overcome many of the so-called short-channel effects which are beginning to stymie continued miniaturization of traditional CMOS technologies. Semiconducting SWCNTs will ultimately occupy an increasingly important place in the modern, commercial chip-design and fabrication landscape whether for relatively low-cost printed transistors, or bleeding-edge integrated circuits.
