  • Abstract
    Our ultrafast optical pump-probe measurements of 2D atomic material MoS2 show that the interband and intraband relaxation dynamics of photoexcited carriers vary significantly as a function of the number of atomic layers. Coherent phonon oscillations are also observed in our measurements.
