摘要

We report an ultrafast increase of the quasi-particle bandgap and effective mass in photoexcited monolayer MoS 2 on HOPG, utilizing extreme-ultraviolet time- and angle-resolved photoemission spectroscopy (XUV-trARPES). Combined with theoretical models, we attribute these compelling band renormalizations to the excitonic effects from bound electron-hole pairs.
