Herein, we report the field emission properties of NiFe2O4/reduced graphene oxide/carbon nanotubes (NGC) and compared them with the field emission properties of NiFe2O4/carbon nanotubes (NC) and NiFe2O4/reduced graphene oxide (NG). The NGC nanocomposite showed a very low turn-on field of ∼0.4 V μm-1 and a high emission current density of ∼8.228 mA cm-2 at a low applied electric field of 1.6 V μm-1. In addition, it exhibited extremely good emission current stability at a preset value of ∼20 μA. The observed very low turn on field of the NGC nanocomposite is due to its lower value of effective work function (1.92 eV), and the results suggest the potential of the synthesized emitter for practical applications in vacuum micro-electronics/nano-electronics.
