Macroelectronic applications of carbon nanotube networks

We report the use of random networks of single-walled carbon nanotubes for electronics on large-area noncrystalline substrates. Thin-film transistors made from such random networks were fabricated and characterized on silicon oxide substrates. We have demonstrated both n- and p-type transistors with an effective mobility that is higher than amorphous Si or organic semiconductors. The carbon nanotube networks were also deposited from solution onto polymeric substrates. The ability to deposit these networks via room temperature methods defines a pathway for lightweight, unbreakable displays and other electronic applications requiring large-area, flexible substrates.
