Coexistence of Urbach?Tail?Like Localized States and Metallic Conduction Channels in Nitrogen?Doped 3D Curved Graphene
Nitrogen (N) doping is one of the most effective approaches to tailor the chemical and physical properties of graphene. By the interplay between N dopants and three?dimensional curvature of graphene lattices, N?doped 3D graphene displays superior performances in electrocatalysis and solar energy harvesting for energy and environmental applications. However, the electrical transport properties and the electronic states, which are the key factors to understand the origins of the N doping effect in 3D graphene, are still missing. We systematically investigated the electronic properties of N?doped 3D graphene by an electric double?layer transistor method. We demonstrated that Urbach?tail?like localized states occupy around the neutral point of N?doped 3D graphene with the background metallic transport channels. The dual nature of electronic states, generated by the synergistic effect of N dopants and 3D curvature of graphene, could be the electronic origin of the high electrocatalysis, enhanced molecular adsorption and light absorption of N?doped 3D graphene.This article is protected by copyright.
