用 6× 6 L uttinger- Kohn模型结合平面波展开方法计算了应变量子阱材料的价带结构 ,分析了用来展开的平面波的数目和周期对能量本征值的影响 .在实际计算中 ,平面波的周期必须选择足够大以保证包络函数在边界处消失 ,同时平面波的数目必须足够多以保证计算结果达到预定的精度 The valence band structure of the strained quantum well material is calculated by the 6 × 6 Luttinger-Kohn model combined with the plane wave expansion method, and the influence of the number and period of the plane wave to be deployed on the energy eigenvalue is analyzed. In the actual calculation, the plane wave The period must be chosen to be large enough to ensure that the envelope disappears at the boundary while the number of plane waves must be sufficiently large to ensure that the calculation results reach a predetermined accuracy
