We report the fabrication of thin film SWNT-FETs using a novel and simple solution process methodology. The SWNTs are dispersed in an organic solution in a narrow bundle structure and form nonaligned arrays which become the channels of FETs. The thin film FETs operate even at low temperature, and have the mobility that is about 100 times greater than those of other solution-processed organic thin film FETs. This simple fabrication process will help develop a novel route for the large-scale liquid phase production of commercially available flexible organic devices.
