Numerical simulation based on first-principles calculations is applied to study the structural characteristics and band-energy properties of the zincblende In x Ga 1Àx N. The deviation parameter of the lattice constant is determined to be )0.004 A. A band gap bowing parameter of 1.890 AE 0.097 eV is
A pseudopotentiel formalism coupled with the virtual crystal approximation (VCA) is applied to study the influence of the composition on the A x B 1Àx C ternary band gap in zinc blende phase. Our theoretical results show that the band gaps are affected by the compositional disorder. We further predi
