摘　　要： 硅烯是单原子层的硅薄膜,具有类石墨烯结构.因此拥有与石墨烯相似的各种奇特的热学、化学、光学和电学性质.近年来,硅烯引起了研究者的广泛关注,作为一种新型的二维狄拉克电子材料,硅烯在理论计算和实验上都取得了不少新的进展.本文主要在前人对硅烯实施边缘钝化、掺杂、外加电场、加应力或者表面官能团修饰和吸附等研究的情况下,结合当前硅烯的研究发展趋势,重点研究了不同掺杂对硅烯性质的影响,并探讨硅烯在未来硅基电子器件的应用前景. Silicene is a single atomic layer of silicon thin film, with a graphene - like structure. Thus, it has va- rious unique thermal, chemical, optical and electrical properties similar to that of graphene. In recent years, si- licene has attracted wide attention of researchers, as a new type of two - dimensional Dirac electronic material, Silicene in the theoretical calculations and experiments has made a lot of new progress. In the case that previous studies of silicene by edge passivation, doping, applying electric field, stress or surface functional group modifi- cation and adsorption , here the effects of different doping on the properties of silieene are focused on research combining with the current trend of development. In addition, the application prospect of silicon - based elec- tronic devices in the future was also discussed.
