The electronic structures of ultra small diameter SWCNTs with B/N, B/P and Al/N co-doping
摘要:
The electronic structures of ultra small diameter SWCNTs with B/N, B/P and Al/N co-doping are investigated by using the first principles theory. The SWCNTs evolve form metallic to semiconducting as a result of the co-doping, in most case the energy gaps increase with increasing the symmetry destruction delta.
