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.
