Abstract. Numerical simulation based on FP-LAPW calculations is applied to study
direct and indirect band gap energy of the cubic Al x Ga 1-x N, In x Ga 1-x N and In x Al 1-x N
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.
Keywords: III-V ternary alloys, band-gap bowing parameter, WIEN(2k).
