Large‐scale, uniform, vertically standing graphene with atomically thin edges are controllably synthesized on copper foil using a microwave‐plasma chemical vapor deposition system. A growth mechanism for this system is proposed. This film shows excellent field‐emission properties, with low turn‐on field of 1.3 V μm −1 , low threshold field of 3.0 V μm −1 and a large field‐enhancement factor more than 10 000.
