Figure 4.8: GaN absorption coefficient near the band gap.
(4.-!.))
Fig. 4.8 displays the absorption data. This experiment measured a larger value for
Q
than the Zhang et at. measurement [13]. Finally, the fitted Sellmeier parameters
accurately reproduce the linear spectral behavior of the GaN/Ah03 film (see Fig. 4.9).
