摘要:

从理论和实验上研究了量子阱中带电激子X-在磁场中的内部自旋单重态和自旋三重态跃迁。所允许的X-跃迁是光致电离的,并且表现出特征性的双峰结构,这反映了在较高朗道能级(LL's)中磁激子连续体的丰富结构。我们讨论了一种新的精确选择规则,一个隐藏的表现形式的平移不变性,管理过渡的带电移动复合物在磁场。

英文摘要:

Internal spin-singlet and spin-triplet transitions of charged excitons X- in magnetic fields in quantum wells have been studied experimentally and theoretically. The allowed X- transitions are photoionizing and exhibit a characteristic double-peak structure, which reflects the rich structure of the magnetoexciton continua in higher Landau levels (LL's). We discuss a novel exact selection rule, a hidden manifestation of translational invariance, that governs transitions of charged mobile complexes in a magnetic field.
