Carbon nanotube transistors get faster
A team of French researchers announced they have made transistors from carbon nanotubes on a silicon substrate.
Scientists explained that these transistors, commonly used as automatic switches, can reach cutoff frequencies of 30 GHz. The previous record, reported by the same team in August 2006, has now been improved by a factor of 4. New prospects are opened up for mainstream applications that require high operating frequencies.
