文摘	The valence subband energies and wave functions of a tensile strained quantum well are calculated by the plane wave expansion method within the 6 * 6 Luttinger-Kohn model. The effect of the number and period of plane-waves used for expansion on the stability of energy eigenvalues is examined. For practical calculation, it should choose the period large sufficiently to ensure the envelope functions vanish at the boundary and the number of plane waves large enough to ensure the energy eigenvalues keep unchanged within a prescribed range.
其他语种文摘	用6 * 6 Luttinger-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。
