Carbon nanotube transistors: size doesn't matter
4) Smaller transistors usually perform better, a fact that has driven the semiconductor industry to shrink the size of silicon transistors by a factor of two approximately every three years. It is anticipated that in about 15 years, they will have become too small to be turned off. Carbon nanotubes are the leading candidate to replace silicon, having already been shown to carry more current per unit of width.
