are discussed in this paper.The linear interpolation method by Moon et al.was applied to calculate the compositional dependence of the energy bandgap for Ⅲ-Ⅴ quaternary alloys.In addition
littejohn gave another method
which was partly different from that reported by Moon et al.According to the two method
we calculated the energy bandgap as a function of the compositions for quaternary alloys Ga

.Comparing the calculated values with the experimental ones
we found that the linear interpolation method is better to calculate the energy bnadgap of Ga
