Carbon nanotubes push transistor limits - Materials Today
Improvements in computer performance are stalling as silicon metal-oxide-semiconductor field-effect transistors (MOSFET) approach their physical limits. To continue to drive performance while reducing power usage, attention is turning to alternative materials like carbon nanotubes (CNTs). But while CNTs offer promising attributes for transistors, the practicalities of fabricating and contacting such devices have limited their applicability to date.
