[SIESTA-L] band lines

Dear Siesta Users, I have a basic question concerning band lines of carbon Nanotubes, it is correct to use the graphene band lines gamma, M, K, gamma in the case of chiral nanotubes (9,2), or BZ folding (2D to 1D) has to be considered by rolling graphene into Nanotubes? any suggestions will be

i think no .the symetry line in 1D like nanotube is gama to X or Z . gamma, M, K, gamma is symetry lines for 2D graphene.there is no line in this directions as i know and test it. On 4/22/13, suf...@nmsu.edu suf...@nmsu.edu wrote: Dear Siesta Users, I have a basic question concerning band
