25_02b/2013Graphene: Controlled Synthesis of Large-Scale, Uniform, Vertically Standing Graphene for High-Performance Field Emitters (Adv. Mater. 2/2013)

Large-scale, uniform, vertically standing graphene film with atomically thin edges (shown in the magnifying glass in the back cover image) is controllably synthesized using methane in a microwave-plasma chemical vapor deposition system. This film shows excellent field-emission properties, as demonstrated by Hong-Jun Gao, Yunqi Liu, and co-workers on page 250. In the lower part of the image, a plane emitter based on this vertically standing graphene film is demonstrated. The small blue spheres between the two plates represent the emitted electrons.
