By solving the effective mass equations using the difference method, taking into account the strain effects and valence band mixing effect, we have compared the band structures, DOS′s of valence band and the optical matrix elements for different shaped wells.
采用差分法求解有效质量方程，考虑轻重空穴的混合效应及应变效应，对三种不同形状的量子阱的能带结构、价带态密度、跃迁矩阵元进行了比较。
