英文摘要	The discovery of two-dimensional transition metal dichalcogenides (2D TMDs) has promised next-generation photonics and optoelectronics applications, particularly in the realm of nanophotonics. Arguably, the most crucial fundamental processes in these applications are exciton migration and charge transfer in 2D TMDs. However, exciton dynamics in 2D TMDs has yet to be studied on a nanophotonic platform and, more importantly, the control of exciton dynamics by means of nanophotonic structures still needs to be explored. Here, we demonstrate the control of exciton dynamics in MoS2 monolayers by introducing a hyperbolic metamaterial (HMM) substrate. We reveal the migration mechanisms of various excitons in MoS2 monolayers. Furthermore, we experimentally demonstrate that the Forster radius can be increased by HMMs, which is consistent with the theory we developed on the basis of nonlocal effects of HMM. This study will provide a significant step forward in enabling 2D TMD nanophotonic hybrid devices.
