Fig. 5. Schematic map of the exciton dynamics channels and the correlated mechanisms.

Fig. 5

The excitons can be divided into two groups with different hole status: X1, X3, X5, and X7 with K↑ hole and X2, X4, X6, and X8 with K′↓ hole. The SOI and e-ph contribute to the exciton transition within one group, and the exchange interaction contributes to the exciton transition between different groups.
