| 摘 要： | 在有效质量近似下，采用无限深势阱模型研究了强受限范围内球形、圆柱形、立方形半导体量子点的形状对受限激子的影响。结果表明对于采用体激子的等效Ｒｙｄｂｅｒｇ能量Ｒ＾＊比较大的材料制备的量子点，其形状带来的影响是显著的。

| Abstract: | The effect of the shape of a quantum dot (QD) on an exciton in a strongly confined QD is investigated. The results show that the energy of a confined exciton varies with the shape of the QD obviously if its binding energy in a bulk material is larger. |

| Keywords: | quantum dot confined exciton strong-confinement |
