TL;DR: Direct measurements of valley relaxation dynamics in single layer MoS2 are reported by using ultrafast transient absorption spectroscopy, showing that strong Coulomb interactions significantly impact valley population dynamics and biexcitons form with more than an order of magnitude larger binding energy compared to conventional semiconductors.
