是的,可以使用半导体模块中的半导体接口,在模型中表征量子阱的特性,参考案例://m.COMSOL.com/model/a-solar-cell-with-inas-quantum-dots-embedded-in-algaasgaas-quantum-wells-100761

可能的原因由很多,如量子阱和垒的材料选择不合理,导致电子和空穴的势垒高度不合适;进一步如量子阱结构的限制能力不足,导致电子和空穴泄漏到其他区域,使得载流子能够通过隧穿或扩散等方式逸出量子阱,也可能是极化效应导致的;具体原因可能需要您联系我们的技术支持,以进一步分析。

文中已经提到:“请注意,由于不考虑材料杂质和其他展宽效应,在对应带隙能量的波长处出现了突然的发射截断。”

如果有机的掺杂的模拟仍旧只需计算电子和空穴的载流子分布的话,应该是可以的,有进一步什么问题您可以通过技术支持联系我们。

案例库模型虽然众多,但不一定能够完全涵盖大家的各方各面,因此我们推荐的主要是可供大家参考的方法和模型示例。如果您需要更有代表性的示例,建议您把完整的需求细节发送到 support@comsol.com,寻求技术支持。

用电场模代替电流密度来表征源可不可以呢?
