    • For undoped diamond, we use the conventional 2 atoms/cell structure with a (3 × 3 × 3) q grid which folds onto the T point of the (3 × 3 × 3) cell.

    • note
    • In the limit of low doping, and as emphasized in Refs. [6,7], zone-center optical phonons are expected to contribute primarily to the e-ph coupling. Such an approximation is at the heart of the q = T deformation potential approach developed by Lee and Pickett in Ref. [7].

    • note
    • We calculate the phonon and electronic state of pristine diamond (2 atoms/cell) and look at the e-ph coupling for a Fermi level located arbitrarily above and below the band gap. A (3 × 3 × 3) and (8 × 8 × 8) grid for the k point and q points was used at convergency.
