    • To access the Zn 4s surface resonance, the use of photon energy greater than ∼4.4 eV would be required, which is prohibited due to intense single-photon emission resulting in the formation of a space-charge region above the sample surface.

    • In this series, the laser power was adjusted by breaking the phasematching condition for sum frequency generation in the LBO nonlinear crystal. Because adjustment of phase-matching by angle-tuning results in a small change in the length of optical material through which the frequency-tripled pulse must pass, we took care to ensure that these changes did not result in significant broadening of the laser pulse

    • We take the LO phonon band to be dispersionless, which is a good approximation in ZnO because the total bandwidth of the LO phonon branch is less than 6 meV: Thoma, K, Dorner, B, Duesing, G, Wegener, W. Solid State Commun. 1974, 15, 1111. Further, only phonons near the zone center take part in polar optical scattering because the magnitude squared of the Fröhlich interaction Hamiltonian scales as Q-2, where Q is the magnitude of the phonon wave vector
    • -2, where Q is the magnitude of the phonon wave vector.
