Nature, it can be fabricated using traditional silicon chip manufacturing techniques. This represents an important step towards a practical realisation of the next generation of microprocessors using carbon nanotubes.
The fabrication of carbon nanotube field effect transistors (CNFETs) is particularly important for the construction of next-generation computers. CNFETs have about ten times more energy efficiency and operate at far higher speeds than silicon FETs. Until now the large-scale production of CNFETs has been dogged by manufacturing defects.
