Graphene exhibits many unique electronic properties owing to its linear dispersive electronic band structure around the Dirac point, making it one of the most studied materials in the last 5-6 years. However, for many applications of graphene, further tuning its electronic band structure is necessary and has been extensively studied ever since graphene was first isolated experimentally. Here we review the major progresses made in electronic structure engineering of graphene, namely by electric and magnetic fields, chemical intercalation and adsorption, stacking geometry, edge-chirality, defects, as well as strain.
石墨烯具有独特的电子性质，这主要归因于其在狄拉克点附近线性分散的能带结构，这使得它成为过去 5-6 年来研究最多的材料之一。然而，对于石墨烯的许多应用来说，进一步调整其能带结构是必要的，自从石墨烯首次被实验分离出来以来，人们就一直在广泛研究这一问题。在这里，我们综述了石墨烯电子结构工程方面的主要进展，即通过电场和磁场、化学插层和吸附、堆积几何形状、边缘手性、缺陷以及应变来实现。
