Structure Of Carbon Nanotubes

Electronic structure of carbon nanotubes with cap and that of the helically coiled nanotubes are studied by the simple tight-binding models. The method of the development map is used for a systematic study of the electronic states. Several remarkable features of these cage structures are found and the relation to the topological disorders due to the disclination centers is discussed, which are inherent to the curved graphitic layer.

The structural stability and electronic properties of silicene-like nanotubes by metal atoms encapsulated were studied by first-principles. The calculations demonstrate that all the structures of nanotubes are stable, expect beryllium doped. Some nanotubes are semiconductor with small value of band gap while others are conductor, because the interaction and hybridizations decrease the band gap. Our electronic structure analysis shows that metal atoms gain electrons and Si atoms lose electrons as a whole, some electrons transferred from Si to metal atoms. We hope that our calculations will provide help to further experimental studies.
