摘要
硅烯是一种零能隙的狄拉克费米子材料,对其能带结构的有效调控进而打开带隙是硅烯进一步器件化的基础.而化学功能化是调控二维材料的结构和电子性质的一种有效方法.本文简要介绍了近几年在硅烯的化学功能化方面取得的进展,主要包括硅烯的氢化、氧化、氯化以及其他几种可能的化学修饰方法.
Silicene exhibits extraordinary physical properties especially Dirac fermion characteristics. However, the zero-gap band structure of silicene hinders its applications in nanoelectronic and optoelectronic devices. It is thus desirable to open a finite band gap in silicene. Chemical functionalization is a commonly used method to tailor the structures and electronic properties of two-dimensional materials. In this paper we review the recent 3-year progress of silicene, including its hydrogenation, oxidization, halogenation, and other methods to modify silicene.
