Abstract :
Graphene film on nickel substrate is synthesized by using thermal chemical vapor deposition method. The field emission characteristics of the graphene film are measured. The turn-on field of 6.4 V/μm and the emission current as large as 1.5 mA is achieved. The current stability of graphene film is very good with fluctuation less than 2.4%. The emission site is found from the protrusion of the graphene on the surface.
