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.
