摘要
In this paper, a model for the band gap energy of the N-rich GaNAs (0 < x <= 0.07) and the As-rich GaNAs (0.95 < x <= 1) is developed. For the N-rich GaNAs, The parameters describing the variation of the CBM and the VBM in the N-rich GaNAs are obtained by fitting the experimental data. For the As-rich GaNAs, the parameters in the model are obtained by fitting the experimental data of the band gap energy. It is found that the band gap evolution of the N-rich energy is different from that of the As-rich band gap energy. The model may be used to calculate the band gap energy of other dilute group III-N-V nitrides.
