Spontaneous exciton dissociation in transition metal dichalcogenide monolayers

Science Advances, Journal Year: 2024, Volume and Issue: 10(5)

Published: Jan. 31, 2024

Since the seminal work on MoS 2 , photoexcitation in atomically thin transition metal dichalcogenides (TMDCs) has been assumed to result excitons, with binding energies order of magnitude larger than thermal energy at room temperature. Here, we reexamine this foundational assumption and show that TMDC monolayers can a substantial population free charges. Performing ultrafast terahertz spectroscopy large-area, single-crystal monolayers, find up ~10% excitons spontaneously dissociate into charge carriers lifetimes exceeding 0.2 ns. Scanning tunneling microscopy reveals photocarrier generation is intimately related mid-gap defects, likely via trap-mediated Auger scattering. Only state-of-the-art quality trap densities as low 10 9 cm −2 does intrinsic exciton physics start dominate response. Our findings reveal necessity knowing defect density understanding photophysics TMDCs.
