Abstract

In pentacene-based bottom-contact field-effect transistors we study the influence of source and drain contact metals (gold, palladium, and platinum) on the morphology and transistor performance. Transistors prepared with Pd electrodes show a reduced contact and sheet resistance, a reduced activation energy, and a closer packed pentacene film in the channel region.
