论文摘要
由于拓扑非平凡的材料的带状结构而产生的结合电子对(BEP)是电荷和旋转载体,带有能量在带隙中。此外,作为复合玻色子,BEP也可以具有完全不寻常的集体特性。在这方面,最重要的是它们衰减时间的问题。考虑到BEPS衰减中的电子 - 电子相互作用,研究了BEP的辐射衰减过程。发现单线BEP的衰减时间位于纳米范围内。三胞胎BEP的辐射衰减是不可能的。
Bound electron pairs (BEPs) arising due to peculiarities of the band structure of topologically nontrivial materials are of interest as charge and spin carriers with energies in the band gap. Moreover, being composite bosons, BEPs can also possess completely unusual collective properties. In this regard, of highest importance is the problem of their decay time. The processes of radiative decay of BEPs are studied, considering the electron-electron interaction in the final state, into which the BEPs decay. It is found that the decay time of singlet BEPs lies in the nanosecond range. The radiative decay of triplet BEPs is impossible.
