    • note
    • Another transition located 0.011 eV above the energy gap was needed to fit the spectra. Since this transition is located above the energy gap (and the much larger excitonic features), it is reasonable to assume that it may be related to another critical point or to a transition from the valence band to a higher lying conduction band.
