Development of strain analysis technique for multi-layer quantum dot solar cells

预测多层量子点太阳电池制作过程中应变场的解析方法。利用该方法给出了材料组合、界面方向、外应变等因素引起的应变场。通过应变分量的组合描述了应变引起的能带变化。考虑了点状材料与基体材料之间的界面弹性，预测了点状材料界面附近的应变场，并对其影响进行了评估。将包含界面弹性的连续力学理论应用于量子点问题。

An analytical method to predict strain fields in multi-layer quantum dots solar cells during its fabrication processes. The strain field due to material combination, interface direction, external strain are given using the developed methods. The change in energy bands due to strain is described through combination of strain components. An interface elasticity between the dot material and matrix material is considered to predict the strain field near the dot-matrix interface and its influence is evaluated. A continum mechanical theory to include the interfacial elasticity is applied to the quantum dot problem.
