摘要

The stability and electronic structure of hypothetical InN nanotubes were studied by first-principles density functional theory.It was found that the strain energies of InN nanotubes are smaller than those of carbon nanotubes of the same radius.Single-wall zigzag InN nanotubes were found to be semiconductors with a direct band gap while the armchair counterparts have an indirect band gap.The band gaps of nanotubes decrease with increasing diameter,similar to the case of carbon nanotubes.
