Abstract
Transistors with a diketopyrrolopyrrole-quarterthiophene (DPP-QT) semiconductor and low-cost Al or Cu electrodes were studied. Albeit a large charge injection resistance exists between DPP-QT and Al or Cu, the resistance was dramatically reduced when unsorted single walled carbon nanotubes (SWCNTs) were blended into the DPP-QT film. This led to a high mobility of 0.64 and 1.1 cm2 V−1 s−1, respectively, for Al and Cu devices, which is similar or even better than the device using gold electrodes (0.78 cm2 V−1 s−1).Keywords
