    • A simple model of the electronic structure of BN-SWNTs has recently been proposed by PRLTAO 0031-9007 10.1103/PhysRevLett.85.1512
    • A simple model of the electronic structure of BN-SWNTs has recently been proposed by P. Král, E. J. Mele, and D. Tomanek, Phys. Rev. Lett. PRLTAO 0031-9007 10.1103/PhysRevLett.85.1512 85, 1512 (2000). Their rather elegant analytical approach is based on an effective-mass approximation and, as such, is valid only in the vicinity of the extrema of the energy bands. This approach can provide a reasonably good description of a number of phenomena in BN-SWNTs, such as, for example, spontaneous polarization (Ref.) or optical absorption (Ref.), which are dominated by the electronic states near those extrema. However, for the reasons indicated in Sec. 2 of the main text, a more general study of the electronic structure of BN-SWNTs has to be used in the description of the collective electronic exitations in these nanotubes. The presence of the energy subbands, dispersed upward and downward in both the v and c bands, plays the key role here, whereas this basic feature is missing in a simple kp band structure model used by Král in their perspective paper cited above.

    • The above discussion possibly sheds some light on the origin of several nondispersive low-energy peaks (below 3.5 eV) observed in the momentum-dependent EELS measurements performed on bulk samples of single-walled CNTs [see PRLTAO 0031-9007 10.1103/PhysRevLett.80.4729

Although there has been a number of attempts to give a theoretical explanation of these features, briefly summarized in Ref., there is still no consensus regarding their true origin. One cannot exclude that these features correspond to the solutions of Eq. 46, which may differ from the zeros of the real part of εL (ω,q). In this case, the low-energy resonant structures observed by Pichler may be associated neither with collective modes nor with excitations between delocalized and localized electronic states, as was initially assumed by Pichler Note that one way to see that the above-mentioned solutions of Eq. 46 are not collective modes is to use Eq. 44 to show that the corresponding ΓL (q) is negative.
