Solution-processed single walled carbon nanotube electrodes for organic thin-film transistors

Airbrushed single walled carbon nanotube (SWCNT) thin films with sheet resistivity <1 kΩ/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.
