    • We use six-unit supercells for zigzag tubes, which is enough to converge the gap shifts to within 0.1 meV in the 0 to 400 K range. Most chiral tubes already have a very long unit cell, therefore it is sufficient to consider just one-unit cell. Also, we have verified, for the (10, 0) and (11, 0) tubes, that our empirical description of the most relevant (low frequency) phonon frequencies and corresponding e-p couplings compare well (within ∼10% and ∼20%, respectively) with those calculated within first-principle methods using the SIESTA code [23].
