Abstract

original image

Carbon films made up of vertically standing, tall graphene strips can be peeled off a substrate. By this route, the film forms a cathode material with a long life and a high field enhancement factor for stable field emission. This film is a further step toward understanding and manipulating the intrinsic field-emission properties of graphene.
