FIG. 1.

Geometric structure of the (9,0)-(18,0) zigzag DWCNTs. The inner and the outer nanotubes, respectively, correspond to the heavy and the light solid curves.

Image of FIG. 2.
FIG. 2.

Band structures without the intertube interactions at (a) and (c) ; those with the intertube interactions at (b) and (d) .

Image of FIG. 3.
FIG. 3.

Magnetic-flux-dependent energy gap in the (a) absence or (b) presence of the intertube interactions.

Image of FIG. 4.
FIG. 4.

Density of states at and in the (a) absence or (b) presence of the intertube interactions. The inset in (a) shows the details near the Fermi level.

Image of FIG. 5.
FIG. 5.

Same plot as Fig. 4, but shown for joint density of states.

Image of FIG. 6.
FIG. 6.

Optical absorption spectra, (a) without or (b) with the intertube interactions at and . Also shown in (a) for clarity are those near the threshold absorption spectra.

Image of FIG. 7.
FIG. 7.

Absorption frequencies at (a) the moderate-frequency range; those at the low-frequency range in the (b) absence or (c) presence of the intertube interactions.
