The Carrier Mobility Study of Graphene Covalently Bonded with Single-Walled Carbon Nanotubes

  • 摘要: 应用密度泛函理论对共价键结合的多孔石墨烯和单壁碳纳米管三维复合材料进行结构优化和能带计算,确定石墨烯和碳纳米管以共价键的形式结合.基于第一性原理计算出石墨烯二维平面上的弹性常数和形变势常数,得到石墨烯电子和空穴迁移率约为104 cm2/(Vs), 比完整的单层石墨烯低1个数量级.该模型可以扩展到共价键结合的碳元素三维空间结构,在未来的有机电子学领域具有广阔的发展前景.
    Abstract: Geometry optimization and calculation about the band structure of the three-dimensional composite, consisting of porous single layer graphene covalently bonded with single-walled carbon nanotubes, are studied in this paper. The connections between graphene and carbon nanotubes are verified to be covalent bond. The elastic constant and deformation potential constant of single-layer graphene-nanotube composite are calculated in deformation potential theory. Its noted that the carrier mobility is about 104 cm2/(Vs) for both electrons and holes. It is about one order of magnitude lower than that of graphene. This composite structure has great future in organic electronics because of its possible extension to three-dimension.
