Characterization Of Field Emission Properties For Nanosheets

Field emission is an electron emission produced by a strong electric field. When the electric field applied to sharp edges on materials, electrons are extracted to vacuum by quantum mechanical tunneling over potential barrier. The efficiency of field emission is mainly determined by electron emitter and many efforts have been dedicated for more stable and smaller field emitters. It has been shown that nanomaterials such as carbon nanotubes and nanowires have advantages compared to bulk materials due to their excellent chemical and physical properties and small size. Graphene is a nanomaterial getting great research attentions due to its superior electrical and mechanical properties such as good electrical conductivity and flexibility. Graphene is a two-dimensional (2D) structure and its thickness is atomically thin which is suitable for field emission effect. In this study, we characterize field emission properties of graphene nanosheets such as graphene and graphene oxide. The result is beneficial for field emission display using graphene nanosheets.
