## Description

- description: We carried out femtosecond time-resolved photoluminescence measurements
    on monolayer MoS2 on a sapphire substrate. The charge density of the monolayer
    MoS2 was evaluated by spectroscopic analysis. Time evolutions of exciton and trion
    luminescence in the femto- and picosecond region were obtained. The rate-equation
    analysis provided the time constant of exciton relaxation to trion, i.e., trion
    formation. This time constant was compared with those of other two-dimensional
    electron systems and is discussed in terms of two dimensionality defined by thickness.
    This study advances the understanding of exciton physics in low-dimensional systems.
