英文摘要：

Silicene is a two-dimensional nanomaterial with Si atoms arranged in a honeycomb lattice.The growth mechanism and research achievement of silicene on the surfaces of Ag（111）,Ir（111）and ZrB2 substrates are introduced,and the similarity and difference of the prepared silicene on different substrates are discussed.At the same time,some of the properties and applications of theoretical predictions for silicone are briefly explained,such as the tunable band gap of silicene in an external vertical electric field and the valley-spin polarization of silicene in the magneto-optical response.All these properties and applications show that silicene can be widely used in future nanoelectronic devices.Finally,the research,development direction and application of the silicene are prospected in the future.The process preparation of the silicene needs to be improved and expanded,and silicene has a better future in the aspect of application.
