Hybrid Tamm monolayer device. a Schematic illustration of the Tamm-plasmon device with the embedded MoSe2 monolayer. The monolayer is capped with PMMA, whose thickness primarily determines the frequency of the device’s optical resonance. b Calculation of the electromagnetic field intensity in the heterostructure. The field distribution in the device is designed to yield optimal overlap with the position of the quantum wells as well as the atomic monolayer. c Reflectivity spectrum of the device prior to capping the structure with Au. The two absorption dips are correlated with the GaAs exciton and the MoSe2 neutral excitonic transition
