Numerical simulation based on first-principles calculation is applied to study the structural characteristics and bandenergy properties of wurtzite In x Ga 1 Γ€ x N. The lattice constants a and c apparently deviate from the VegardΓ•s law. The deviation parameter is 0.047 Β± 0.011 A ˚for the a lattice c

This paper gives the composition dependence of the bandgap energy for highly doped n-type Al x Ga 1Γ€x N. We report results of the bowing parameter obtained using a random simulation. Three groups of Al x Ga 1Γ€x N semiconductors were considered and which are distinguishable by their non degenerate or
