Bandgap Eg , affinity X, permittivity ϵ, and densities of states in the conduction band NC and in the valence band NV of GaN and InN [29–31]. The absorption is given by equation (2), the C and D values being fitting from experimental data , with Eph the incident photons energy and Eg the InGaN bandgap for a given indium composition x.
