Organic thin-film transistors are interesting candidates for the realization of low-power displays and other electronics on unconventional and flexible substrates. However, the adoption of organic TFTs in these applications has yet to be realized primarily due to high contact resistance. Here, we present a method for fabricating flexible organic TFTs with contact resistance as low as 29 Omega cm, a record for organic TFTs. In addition, these TFTs show other remarkable or record characteristics such as high on/off current ratio (as high as 10(10)), low subthreshold swing (as small as 59 mV/decade at 292 K), small stage delay (79 ns measured in an 11-stage ring oscillator) and high transit frequency (as high as 21 MHz). These results were obtained in ambient measurement conditions at low voltages of around 3 V.
