a b s t r a c t Airbrushed single walled carbon nanotube (SWCNT) thin films with sheet resistivity <1 kX/ sq. and transparency>80 % are used as electrodes for pentacene and regioregular poly(3-hexylthiophene) (P3HT) thin-film transistors (TFTs). Airbrushed SWCNT electrodes show low contact resistance in a bottom-contact configuration, comparable to (in the case of P3HT) or lower than (in the case of pentacene) Au bottom-contacts. The results show that airbrushed CNT electrodes yield similar performance to CVD-grown CNT electrodes. techniques for processing flexible, transparent electronics [2]. Currently oxide semiconductors (e.g. indium tin oxide or ITO) are widely used as transparent, conducting films in organic electronics applications. These materials are inher-sively without vacuum equipment through solution tech-niques such as microfiltration [4,10], airbrushing [11–13], dipcoating [12,14], and electrophoretic deposition [15]. Understanding the electrical properties and limitations of the SWCNT/organic semiconductor interface is impor-tant to fully realize applications of transparent, conducting SWCNT films such as organic light-emitting diodes [3,4,16
