What is Role of Defects in Ultrafast Charge Recombination in Monolayer <Mml:math Xmlns:mml=" about?
In this paper, we have systematically studied the role of point defects in the recombination time of monolayer MoS 2 using time-dependent ab initio nonadiabatic molecular dynamics simulations. Various types of point defects, such as S vacancy, S interstitial, Mo vacancy, and Mo interstitial have been considered. We show that defects strongly accelerate the electron-hole recombination, especially interstitial S atoms do that by three orders of magnitude higher compared to pristine MoS 2 . Mo defects (both vacancy and interstitial) introduce a multitude of de-excitation pathways via various defect levels in the energy gap. The results of this study provide some fundamental understanding of photoinduced de-excitation dynamics in presence of defects in highly technologically relevant 2D MoS 2 .
