    • note
    • A broadening close to 200 meV is needed in the calculation to reproduce the experimental spectrum. However, the theoretical curve in Fig. 3(a) has been obtained using a smaller broadening γ = 100 meV [as at Si(100) [31]] in order to better distinguish the excitonic peaks. The larger experimental broadening at C(100) may be due to several effects, as multiple domains, steps, H-induced disorder, and thermal vibrations.
