Abstract :
A single few-layer graphene (FLG) sheet is synthesized on a tungsten tip by using microwave plasma enhanced chemical vapor deposition method. The sheet density of FLG on a tungsten tip is controlled by the substrate surface structure and local plasma density. This method provides a new way to fabricate a field emission point electron source.
