Graphene, as a typical two-dimensional nanometer material, has shown its uniqueapplication potential in electrical characteristics, thermal properties, and thermoelectric propertiesby virtue of its novel electronic structure. The field of traditional material modification mainlychanges or enhances certain properties of materials by mixing a variety of materials (to form aheterostructure) and doping. For graphene as well, this paper specifically discusses the use oftraditional modification methods to improve graphene's electrical and thermoelectrical properties.More deeply, since graphene is an atomic-level thin film material, its shape and edge conformation(zigzag boundary and armchair boundary) have a great impact on performance. Therefore, thispaper reviews the graphene modification field in recent years. Through the change in the shape ofgraphene, the change in the boundary structure configuration, the doping of other atoms, and theformation of a heterostructure, the electrical, thermal, and thermoelectric properties of graphenechange, resulting in broader applications in more fields. Through studies of graphene's electrical,thermal, and thermoelectric properties in recent years, progress has been made not only inexperimental testing, but also in theoretical calculation. These aspects of graphene are reviewed inthis paper.
石墨烯作为一种典型的二维纳米材料，凭借其新颖的电子结构，在电学特性、热学性质和热电性质方面展现出独特的应用潜力。传统材料改性领域主要通过混合多种材料（形成异质结构）和掺杂来改变或增强材料的某些性能。对于石墨烯而言，本文具体探讨了使用传统改性方法来改善石墨烯的电学和热电性能。更深入地讲，由于石墨烯是一种原子级薄膜材料，其形状和边缘构象（锯齿形边界和扶手椅形边界）对性能有很大影响。因此，本文综述了近年来的石墨烯改性领域。通过改变石墨烯的形状、边界结构构型的变化、其他原子的掺杂以及异质结构的形成，石墨烯的电学、热学和热电性质发生改变，从而在更多领域有更广泛的应用。通过近年来对石墨烯电学、热学和热电性质的研究，不仅在实验测试方面取得了进展，在理论计算方面也有进展。本文对石墨烯的这些方面进行了综述。
