Janus 2维Ⅳ主族烯类的研究进展
Research Progress in Janus 2D Group-Ⅳ Materials
摘要
Abstract
Since the successful isolation of graphene,its outstanding properties in mechanics,electronic transport,and thermoelectricity have attracted scholars to carry out extensive research.Silicene and germanene,as 2D group-Ⅳmaterials similar to graphene,have also widely concerned.However,the zero-band gap or small band gap of these materials limits their application range.The 2D out-of-plane mirror symmetry in emerging Janus materials is broken by asymmetrical functional group modifications,thus the band gap of this class of materials is opened and unique properties are produced.In this paper,the electronic structure and macroscopic physical properties of graphene,silicene,and germanene are introduced and analyzed,and some possible schemes to open the band gap of these materials are briefly summarized.Then,the effects of semi-hydrogenation,semi-halogenation,Janus H/X cofunctionalization and dual-halogenation on the crystal structure,electronic and energy band properties of Janus 2D group-Ⅳmaterials are summarized.The changes in energy band types,magnetic and optical properties of Janus 2D group-Ⅳmaterials regulated by asymmetric functionalization were discussed,and their internal physical mechanisms are analyzed.Finally,the research status and future prospects of Janus 2D group-Ⅳmaterials are summarized.关键词
