Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Large‐scale, uniform, vertically standing graphene with atomically thin edges</bold> 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1p96jvwb" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
