Abstract

Using the first-principles study, we calculate the electronic band structure of metallic carbon nanotubes (MCNTs) with B/N co-doping. We show the formation energies which suggest that the B/N co-doping configuration is the energetically stable structure. We find that the electronic structure properties depend on the doping concentration of MCNTs, as well as the doping position. Energy gap opens rapidly when the symmetry breaking of MCNTs happens. These unconventional doping effects could be used to design novel nanoelectronic devices.
