| 摘 要： | 介绍了量子点阵列的有限元分析方法，分析了二维透镜形2×2自组织相干量子点阵列的应变场分布，给出了不同方向上和不同位置处量子点阵列的应变运算结果. 通过对结果的讨论得出结论：当量子点间的横向距离与其线度可比拟时，量子点阵列中各量子点内的应变不受周围其他量子点的影响.v

| Abstract: | The elastic strain fields in the 2×2 array self-organized coherent quantum dots (QD) structures were investigated in detail by the finite element analysis for lens QDs. Strains of quantum dots array along different directions at different height in QDs were presented. Conclusions show that the strain of QD will not be influenced by the other of the QDs array when the size is similar to the distances between the QDs in the array. |
