Mancevski added, The nanotube tip needs to have the right diameter, and be oriented properly. Since then, the company has executed several projects funded by the National Scienc Foundation, the Army Research Office, the National Institute of Standards and Technology and SEMATECH. Xidexs process allows for great control over the CNT tip structure such as diameter, length and orientation, which is crucial for the uses desired by SEMATECHs member companies. Individual CNTs are hollow tubes formed by hexagons of carbon atoms, and are about 10,000 times thinner than human hair. Additional information is available at www. xidex. com..

Single CNT tips are electronically conductive and can also be chemically modified, it is also quite possible to manufacture specialized tips for advanced electrical and chemical testing. Compared to conventional silicon tips, CNT tips can be made with much smaller end radii and very high aspect ratios, enabling them to reach into the difficulttoaccess spaces between microscopic features, Xidex officials explained. Keith J. Recent rankings position it as one of the top chemistry departments in the country for graduate programs and funding for research and development.

The work is being done with AMRC funding, under contract with SEMATECH. Single CNT tips are also extremely wearresistant compared to silicon tips, extending their useful life and enabling higherprecision measurements, officials said.

Josey Fellow in Energy Studies in the Department of Chemistry and Biochemistry at The University of Texas at Austin offers opportunities for worldclass research across broad range of chemical and biochemical fields. The time is right to introduce commercially available CNT tips for widespread use, said Paul Additional information is available at www. xidex. com. The AMRC was launched in by the State of Texas and SEMATECH to work with the UT System and other Texas universities in investigating promising new semiconductor technologies that will ensure the states hightech future.
