Carbon Nanotube Electronics

P. Avouris
IBM Research Division, US

Keywords: carbon nanotube, electronics

Abstract:
Carbon nanotubes are nearly ideal, one-dimensional systems with unique properties that recommend them for applications in nanoelectronics. I will discuss the electronic structure and electrical properties of metallic and semiconducting carbon nanotubes and the fabrication and performance of nanotube devices. Results of electrical transport studies, scanning probe experiments, and theoretical modeling will be used in addressing such issues as the nature of the switching in nanotube transistors, the nanotube-metal electrode interaction, the resulting charge transfer and the role of co-adsorption and the ambient environment on the transport properties. I will then discuss how these findings can be utilized to produce high performance p-type, n-type and ambipolar nanotube field-effect transistors and intra-nanotube logic circuits. The performance and potential of nanotube devices will be compared with those of silicon devices and of devices based on other one-dimensional systems, such as boron nitride nanotubes. I will end with a brief discussion of new developments in the synthesis of carbon nanotubes.
