摘要
The one-dimensional hybrid structures of C36 encapsulated in zigzag single-wall carbon nanotubes (C36@(n,0)) have been investigated using ab initio self-consistent-field crystal orbital method based on the density functional theory. The research focuses on the change of geometric and band struc- tures for the nanotubes upon C36 encapsulation. The obtained results show that the introduction of C36 can modify the electronic properties of CNT. The diameter of carbon nanotube plays an important role in the geometric and electronic properties of the peapod structures.
