石墨烯是纳米技术中最有前途的材料之一。具有较高原子晶格完备性的石墨烯样品具有优异的电子和机械性能，但在生长或加工过程中可能出现的结构缺陷会降低石墨烯器件的性能。然而，与完美的偏差在某些应用中可能是有用的，因为它们使定制石墨烯的局部属性和实现新功能成为可能。本文综述了石墨烯中点缺陷和线缺陷的研究现状，重点介绍了石墨烯在本征缺陷周围重建晶格的独特能力，从而产生了有趣的效应和潜在的应用前景。文中还讨论了外来原子等非本征缺陷，这些缺陷对于设计具有特殊性质的石墨烯器件同样重要。
Graphene is one of the most promising materials in nanotechnology. The electronic and mechanical properties of graphene samples with high perfection of the atomic lattice are outstanding, but structural defects, which may appear during growth Or processing, deteriorate the performance of graphene-based devices. However, deviations from perfection can be useful in some applications, as they make it possible to tailor the local properties of graphene and to achieve new functionalities. In this article, the present knowledge about point and line defects in graphene are reviewed Particular emphasis is put on the unique ability of graphene to reconstruct its lattice around intrinsic defects, leading to interesting effects and potential applications. Extrinsic defects such as foreign atoms which are of equally high importance for designing graphene-based devices With dedicated properties are also discussed.
