在有效质量近似下
从理论上研究了非对称双三角量子阱的拉曼散射。推导了导带子带间电子跃迁的微分散射截面表达式
以GaAs/Al

As材料为例进行了数值计算。结果表明
散射光谱不仅与掺杂浓度有关
而且与双量子阱的不对称性有关
随着量子阱不对称性的增加或掺杂浓度的减少
散射峰发生了红移。本工作对设计新型微电子和光电子器件有一定的指导意义。
Electron Raman scattering (ERS) is investigated theoretically in asymmetric triangular double quantum wells (ATDQWs) within the framework of effective-mass approximation. The differential cross-section (DCS) is derived. Numerical calculations are performed for GaAs/Al

As ATDQWs. Results show that the ERS spectrum depends not only on the doping content but also on the asymmetry of ATDQWs. The spectrum yields a red shift with increasing the asymmetry of quantum wells or decreasing the Al doping content.
