Ultrathin Films of Single Walled Carbon Nanotubes for Analog RF and Digital Electronics
Abstract:

The excellent intrinsic properties of single-walled carbon nanotubes (SWNTs), together with the ability to integrate them on a wide range of substrate types, create opportunities for use in many areas of electronics. For these applications, sub-monolayer coverages of aligned arrays or random networks of SWNTs can provide effective thin-film semiconductors for scalable circuit integration. This talk describes our research in this area, with a focus on (1) guided growth of large scale, horizontally aligned arrays of SWNTs, (2) charge transport in arrays and percolating random networks, (3) device and circuit implementations, including high mobility transistors with GHz switching speeds, carbon nanotube transistor radios and medium-scale digital logic circuits.
