“…B. In agreement with recent observations [73], we assume that the z-components of the dipoles d z ϕ µ r=0 ≈ 0 in the TMDCs, and consider the molecular dipoles to be aligned with respect to the inplane coordinate, i.e. d 12 z ≈ 0.…”

“…This is much smaller than the photon wavelength 933 nm and, therefore, we expect the dipole approximation to be entirely valid in this case. Since the optical dipole of IX is in-plane [39], the coupling between the cavity mode and the different trapped IX sites is described by the Tavis-Cummings model…”

“…With interlayer hopping, holes in layer 2 can form a bright exciton with electrons in CB2 in layer 1. Such spatially indirect excitons have been reported in other multilayer TMDCs like MoS 2 , MoSe 2 , WSe 2 and heterobilayers. , But so far they have not been observed in any room temperature PL spectra, likely due to the low quantum efficiency in those indirect gap multilayer TMDCs. In bilayer MoTe 2 , the energy separation (Δ E 1 ) between the two lowest conduction bands at the K valley is 27 meV at 0 strain, close to the separation (33.9 meV) we see between P 1 and P 2 in Figure b.…”
