Carbon nanostructures have been much sought after for cold-cathode field emission applications. Herein a printing technique is reported to controllably nanostructure chemical vapor deposited graphene into vertically standing fins. The method allows for the creation of regular arrays of bilayer graphene fins, with sharp ridges that, when printed onto gold electrodes, afford a new type of field emission electron source geometry. The approach affords tunable morphologies and excellent long term and cyclic stabilities.
碳纳米结构一直以来都备受追捧，被广泛应用于冷阴极场发射领域。本文报道了一种打印技术，可以将化学气相沉积的石墨烯可控地纳米结构化，形成垂直的鳍状结构。该方法可以制备出规则排列的双层石墨烯鳍状结构，其边缘非常锐利。当将其打印到金电极上时，可以得到一种新型的场发射电子源结构。该方法具有可调的形态，并且具有优异的长期和循环稳定性。
