Substrate-Dependent Exciton Diffusion and Annihilation in Chemically Treated MoS 2 and WS 2
Copyright © 2020 American Chemical Society. Atomically thin semiconductors such as monolayer MoS2 and WS2 exhibit nonlinear exciton-exciton annihilation at notably low excitation densities (below ∼10 excitons/μm2 in exfoliated MoS2). Here, we show that the density threshold at which annihilation occ...
