Quantum beat spectroscopy reveals coherent coupling of spin-singlet and spin-triplet interlayer excitons, highlighting key interactions in WSe2-MoSe2 heterobilayers.
Utilizing quantum beat spectroscopy and using temperature as a control knob, we have observed the quantum beat signal as a clear signature of coherent coupling between the spin-singlet and spin-triplet interlayer excitons of WSe 2 -MoSe 2 heterobilayers.
