摘要 基于第一性原理的密度泛函理论,计算并分析了铝氮共掺杂小半径碳纳米管的电子结构.结果表明,铝氮共掺杂的情况下,更容易形成相邻的铝氮对.在掺杂的七种位置中,电子性质都发生了很大的变化,原来的金属性碳纳米管转变为半导体性质.为了更好的理解其电子性质的变化,我们分析其能带结构和态密度. The electronic structures of AI/N co - doping single - walled carbon nanotubes with ultra small diame- ter are investigated by using the first principles theory. The results indicate that they lean to form adjacent A1/N pair. The electronic properties have the significant changes for all the seven doped structures. In addition, AI/N co -doping can convert the carbon nanotubes from metallic into semiconducting. To understand the electronic properties deeply, we study the band structures and density of states.
