Ultrafast XUV ARPES studies of electron and exciton dynamics in the transition-metal dichalcogenide MoSe2
We exploit ultrafast extreme-UV angle-resolved photoemission spectroscopy (XUV ARPES) for sensitive studies of non-equilibrium carrier dynamics in MoSe2. The experiments reveal inter-valley scattering and provide first evidence for the observation of band-gap excitons in ARPES.
