## Description

- description: This letter reports a time-resolved pump-probe reflectance spectroscopic
    study on moiré excitons in a twisted monolayer WS₂/WSe₂ heterostructure. By probing
    at the resonant energies of intralayer excitons, we observed their distinct temporal
    tracks under the influence of interlayer excitons, which we attribute to the discrepancy
    in spatial distribution of the intralayer excitons in different layers. We also
    observed that intralayer moiré excitons in the WSe₂ layer differ at decay rate,
    which reflects different locations of Wannier-like and charge-transfer intralayer
    excitons in a moiré cell. We concluded that the interlayer moiré excitons form
    within a few picoseconds and have lifetimes exceeding five nanoseconds. Our results
    provide insights into the nature of moiré excitons and the strain’s significant
    impact on their behaviour in twisted heterostructures, which could have important
    implications for the development of novel optoelectronic devices.
