Efficient Exciton–Plasmon Conversion in Ag Nanowire/Monolayer MoS₂ Hybrids: Direct Imaging and Quantitative Estimation of Plasmon Coupling and Propagation

Plasmon coupling and propagation between metallic nanowires (NWs) and atomically thin transition-metal dichalcogenide semiconductors are demonstrated using Ag NW/MoS2 hybrids. The high exciton–plasmon coupling efficiency with large throughput of MoS2 excitons allows quantitative assessment of plasmon waveguide performance. Monolayer MoS2 allows real-space visualization of the propagating plasmons along the NW via direct plasmon–exciton coupling.
