摘要
综述了包括石墨烯、磷烯及由碳、氮、磷3种元素所构成的二维材料的研究现状、发展水平、存在问题及发展趋势.这些二维材料展现出多样的结构和电子性质,如γ-PC和P2/m相的C4N是半金属,α0-PC、β0-PC和DB C4N的能带具有狄拉克锥结构,β0-PC、P3C、C9N4和pc-C3N2是金属,P2C3是一种具有双Kagome能带结构的出色传输材料.更多的材料具有半导体性质,在电子、光学、热电、催化、能源等领域具有良好的应用前景.尽管此类材料取得一定研究进展,但急需发展宽带隙和高迁移率二维材料,以满足高能电子装置发展的需要.由碳、氮、磷组成的三元二维材料有望成为新奇结构和独特性质的材料.
This review mainly introduces the research status,development level,existing problems and development trends of graphene,phosphorene and two-dimensional materials composed of carbon,nitrogen and phosphorus.These two-dimensional materials exhibit diverse structures and electronic properties:γ-PC and P2/m C4N are semimetals;the energy band ofα0-PC,β0-PC and DB C4N have a Dirac cone structure;β0-PC,P3C,C9N4 and pc-C3N2 are metals;P2C3 is an outstanding transport characteristic material with double Kagome bands;other materials have semiconductor properties,and demonstrate good application prospects in the fields of electronics,optics,thermoelectricity,catalysis,and energy.Although some progress has been made such materials,it is urgent to develop wide band gap and high mobility two-dimensional materials to meet the needs of the development of high-energy electronic devices.The ternary two-dimensional material composed of carbon,nitrogen and phosphorus is expected to have novel structure and exotic properties.
