Abstract

original image

Pentacene field-effect transistor performance can be improved by modifying metal electrodes with self-assembled monolayers. The dominant role in performance is played by pentacene morphology rather than the work function of the modified electrodes. With optimized processing conditions, hysteresis-free transfer curves with very small switch-on voltages are obtained for single-monolayer pentacene active channels.
