Numerical simulation based on FP-LAPW calculations is applied to study
direct and indirect band gap energy of the cubic AlxGa₁₋xN, InxGa₁₋xN and InxAl₁₋xN
alloys.The direct and indirect band-gap bowing parameter is also calculated, and the
values obtained are very important, as we find a strong dependence of the bowing
parameter on the composition.
