The system we selected is the positive donor ion located in the centers of GaAslGaAsAl quantum well (doped density of Al is 0.33) in the process of calculation. We take the center of well as the origin of coordinates. We noticed that the electron"s effective mass is different in the well and in the barrier, but didn"t pay attention to the mismatch of the dielectric constant.

在计算过程中，我们选取的体系是0中心的正施主离子处于 GaAS／GaAsAI（其中以的搀杂浓度为 0.3 3）量于阶中心，把量子阶中心选作坐标原点，考虑了在阶中和垒中电子的有效质量的不同，但没有考虑在阶中和垒中介电常数的失配性。
