Emergent Trion-Phonon Coupling in Atomically-Reconstructed MoSe${}_2$-WSe${}_2$ Heterobilayers

Sebastian Meier, Yaroslav Zhumagulov, Matthias Dietl +8

In low-temperature resonant Raman experiments on MoSe${}_2$-WSe${}_2$ heterobilayers, we identify a hybrid interlayer shear mode (HSM) with an energy, close to the interlayer shear mod…
