Article Preview

In the paper, a model is developed to discribe the band gap energy of Ⅲ nitride alloys. A new parameter A is used to discribe the band gap bowing. The new bowing parameter A is obtained by fitting the experimental values of the band gap energy. AAlGaN =0.46, AInGaN =0.59 and AInAlN =1.90 are obtained by fitting the experimental values of the band gap energy for AlGaN, InGaN and InAlN, respectively. The model is also suitable to discribe the band gap energy of other Ⅲ-Ⅴ ternary alloys.
