19. With the 1 orbital TB, Green's functions are calculated by the recursion method (Ref. 21), and the charges are obtained by using analytic continuation technique explained in Ref. 22. Though the capped NT's treated with 4 orbitals TB have finite lengths, those treated with 1 orbital TB are semi-infinite to obtain the continuous spectra as Ref. 11. Differences of the charge between the two TB, however, are not mainly due to the difference of the length but the orbital mixing caused by curvature.
