Abstract: Field emission of reduced graphene oxide coated on polystyrene film is studied in both parallel and perpendicular configurations. Low turn-on field of 0.6 V/μm and high emission current density of 200 mA/cm2 are observed in perpendicular configuration (along the cross section), whereas a turn-on field of 6 V/μm and current density of 20 μA/cm2 are obtained in parallel configuration (top surface). The emission characteristics follow Fowler-Nordheim (FN) tunneling and the values of enhancement factor estimated from FN plots are 5818 (perpendicular) and 741 (parallel). Furthermore, stability and repeatability of the field emission characteristics in perpendicular configuration are presented. © 2013 American Institute of Physics.
