Recent reports suggest that graphitic tubules with |
|
diameters on the order of fullerene diameters have been |
|
synthesized. Such small-diameter tubules should have |
|
electronic properties related to those of two-dimensional |
|
graphite. We demonstrate by comparison with results from |
|
a first principles, self-consistent, all electron |
|
Gaussian-orbital based local-density functional approach |
|
that an all-valence tight binding model can be expected |
|
to give a reasonable description of the electronic states |
|
of these tubules. In analyzing both high-symmetry tubules |
|
and lower-symmetry chiral tubules, we see that a |
|
relatively high carrier density could be expected for |
|
many of these structures. |
