Exciton radiative lifetime in transition metal dichalcogenide monolayers

We have investigated the exciton dynamics in transition metal dichalcogenide monolayers using time-resolved photoluminescence experiments performed with optimized time resolution. For $\mathrm{MoS}{\mathrm{e}}_{2}$ monolayer, we measure ${\ensuremath{\tau}}_{\mathrm{rad}}^{0}=1.8\ifmmode\pm\else\tex... View More
