a The maximum radiative rates obtainable by adjusting the graphene Fermi level, for the different TMD materials and number of layers in the quantum well (N). b The Purcell factors corresponding to the maximal radiative rates in (a). Radiative emission rates as a function of graphene Fermi level for 2 (c), 3 (d), 4 (e), and 5 (f) layers. g Coupling efficiency, η = Γrad/Γtot, evaluated for EF giving the maximum radiative rate. All rates were calculated using the generalized Weisskopf–Wigner MQED-DFT framework.
