Suppression of nucleation around a gold electrode during pentacene growth on a SiO 2 channel is found by photoemission electron microscopy. Mass flow is driven by the difference between the molecular orientations on SiO 2 and gold. The poor connectivity at the channel/electrode boundary causes degradation in the performance of a field‐effect transistor, which is found to be improved by self‐assembled monolayer treatment on the electrode (see figure; thickness in monolayers (ML)).
