Abstract

We demonstrate solution processable large area field effect transistors (FETs) from aligned arrays of carbon nanotubes (CNTs). Commercially available, surfactant free CNTs suspended in aqueous solution were aligned between source and drain electrodes using ac dielectrophoresis technique. After removing the metallic nanotubes using electrical breakdown, the devices displayed p-type behavior with on-off ratios up to similar to 2x10(4). The measured field effect mobilities are as high as 123 cm(2)/V s, which is three orders of magnitude higher than typical solution processed organic FET devices.
