Abstract:We have used dense, perfectly aligned arrays of long, perfectly linear SWNTs as an effective thin film semiconductor suitable for integration into transistors and other classes of electronic devices. These types of devices show excellent electric performance with mobilities and scaled transconductances approaching ∼2,000 cm2 V-1 s-1 and ∼3,000 S m-1, respectively. MOS and CMOS logic gates and mechanically flexible transistors on plastic were also demonstrated. Finally we have studied the high frequency performance of transistors that use aligned SWNT arrays. For the first time we have observed power gain from SWNT transistors. This achievement allows us to build all of the key functions of analog electronics, including resonant antennas, fixed RF amplifiers, RF mixers and audio amplifiers. Combining these components we have built the first carbon nanotube radio. These results represent important first steps to practical implementation of SWNTs in high speed analog circuits.
