High Value Semiconducting Carbon Nanotubes
Moore's Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore's Law in its tracks within 20 years. New materials and techniques must be found to complement and increase the capabilities of the current... view more... (2004-07-09)
