Abstract: First-principles calculations based on a density functional theory were carried out to investigate electronic properties of BC2 N nanotubes. It was found that the strain energy of the BC2 N nanotube depends on the diameter but independent of the chirality of the tube. The electronic properties, however, are closely related to both the diameter and chirality of the tube. Generally, all BC2 N nanotubes, except for a few with very small diameters, are direct gap semiconductors. Both the top valence band and the bottom conduction band are formed by carbon p orbitals normal to the tube surface. © 2006 The American Physical Society.
