Abstract

The performance of multi-layer graphene (MLG) films as alternative electrodes for pentacene organic field effect transistors (OFETs) was investigated and compared to conventional OFETs with Au electrodes. We observed the enhancement of charge injection for graphene-electrode pentacene OFETs (GR-pentacene OFET), as evidenced by decreased contact resistance and lower barrier height than in the case of Au-electrode pentacene OFETs (Au-pentacene OFET). Our results show that the beneficial orientation of the interfacial dipole layer is responsible for the improved performance of the graphene-electrode OFETs compared to Au-pentacene OFETs. This study will help to establish graphene-based thin films as efficient electrode materials for organic electronic devices.
