摘要: 根据DFT/B3LYP的计算结果,从能带、态密度和电子结构的变化,讨论了以C_C键替换B_N键的二碳和四碳掺杂的硼氮纳米管的导电性.结果表明,替换后硼氮纳米管的导电性能增强,并且可以通过控制替换的量来调节管的半导体性能

关键词: 碳掺杂硼氮纳米管, 能带, 态密度, 电子结构, DFT/B3LYP计算

Abstract: From the changes in energy band, density of state(DOS) and the electronic structure calculated by the DFT/B3LYP method, the conductivity of carbon doped boron-nitride nanotube(BNNT), which is formed by C_C bond substituting B_N bond, was discussed. The results indicate that the substitution will strength the conductivity of the tube, and its semi-conductivity might be adjusted by controlling the substitution.

Key words: Carbon doped boron-nitride nanotube(BNNT), Energy band, Density of state(DOS), Electronic structure, DFT/B3LYP calculation
