Abstract

Pentacene organic field-effect transistors with multilayer graphene electrodes exhibit a lower contact resistance and lower charge-injection barrier height than those with conventional Au electrodes. This enhancement in performance is related to the favorable dipole layer formation at the graphene/pentacene interface.
