Exciton Linewidth
Due to strong multiparticle interactions in 2D transition metal dichalcogenides at room temperature, their homogeneous exciton linewidths are significantly broadened, degrading the quality of their excitonic mode and emission. In article number 2108721, Yuebing Zheng and co‐workers achieve near‐intrinsic exciton linewidth in monolayer WS2 at room temperature, approaching the theoretical...
The homogeneous exciton linewidth, which captures the coherent quantum dynamics of an excitonic state, is a vital parameter in exploring light–matter interactions in 2D transition metal dichalcogenides (TMDs). An efficient control of the exciton linewidth is of great significance, and in particular of its intrinsic linewidth, which determines the minimum timescale for the coherent manipulation of...
