How does exchange-induced Valley-mixing of exciton affect light-matter interactions in TMD-ml?

The exchange-induced valley-mixing of exciton leads to the unusual linear energy dispersions of exciton, which, as shown later, directly impacts the generic light-matter interactions of TMD-ML’s, including that for the exciton-mediated energy transfer.

Are atomically thin TMD-mL's energy transfer influenced by Dark excitons?

Remarkably, the energy-transfer responses of atomically thin TMD-ML’s are shown to be dictated by the momentum-forbidden dark excitons rather than the commonly recognized bright ones.

Why are dark exciton states important?

Dark exciton states show great potential in condensed matter physics and optoelectronics because of their long lifetime and rich distribution in band structures. Therefore, they can theoretically serve as efficient energy reservoirs, providing a platform for future applications.
