用赝势方法计算了闪锌矿结构中GaxIn1−XP三元合金的光学性质。总的来说，我们的结果与文献中的现有数据之间的一致性是合理的。所研究特征的组成依赖关系对大多数所研究特征表现出非单调行为。对这些发现的原因进行了讨论。此外，研究了组成无序对感兴趣特征的影响，并发现这对于计算GaxIn1−XP的光学性质是重要的。
A pseudopotential scheme, which incorporates compositional disorder as an effective potential, is used so as to calculate the optical properties of GaxIn1−xP ternary alloys in the zinc-blende structure. Generally, the agreement between our results and the existing data in the literature is reasonable. The composition dependence of the studied features showed a non-monotonic behaviour for most studied features. Reasons for these findings are discussed. Moreover, the effect of the compositional disorder on the features of interest has been examined and found to be important for the calculation of optical properties of GaxIn1−xP.
