“…Atomically thin transition-metal dichalcogenides (TMDs) such as MoS 2 , − direct-band-gap two-dimensional materials, have attracted great interest and exhibited promising applications in field-effect transistors, , solar cells, photodetectors, − light-emitting devices, strong-coupling regimes, plasmon–exciton coupling and surface-enhanced Raman scattering (SERS), , due to their extraordinary physical properties. Nevertheless, their low quantum efficiency and weak light absorption have been bottlenecks in these applications.…”
