Chemical modification of silicene

Abstract

Silicene is a two-dimensional material, which is composed of a single layer of silicon atoms with sp2-sp3 mixed hybridization. The sp2-sp3 mixed hybridization renders silicene excellent reactive ability, facilitating the chemical modification of silicene. It has been demonstrated that chemical modification effectively enables the tuning of the properties of silicene. We now review all kind of chemical modification methods for silicene including hydrogenation, halogenation, organic surface modification, oxidation, doping and alloying. The effects of these chemical modification methods on the geometrical, electronic, optical and magnetic properties of silicene are discussed. The potential applications of chemically modified silicene in a variety of fields such as electronics, optoelectronics and magnetoelectronics are introduced. We finally envision future work on the chemical modification of silicene for the sake of further advancing the development of silicene.
