Fig. 3: Calculated transmittance spectra of monolayer MoSe2 modulated by lattice deformations and derived optical modulations.

From: K-point longitudinal acoustic phonons are responsible for ultrafast intervalley scattering in monolayer MoSe2

Fig. 3

The optical modulations are induced by: a A1′(Γ), b LA(K), and c LA(M) modes. Left panel: transmittance spectra of monolayer MoSe2 with and without the lattice deformations (Q = ± 0.1, ±0.3, and 0, respectively) and the laser spectrum (gray shading) used in the experiment. Middle panel: the differential transmittance ΔT(Q)/T0 as a function of the generalized displacement Q evaluated by integrating the experimental laser spectrum with the calculated transmittance spectra (see Methods). Right panel: simulated time-evolved differential transmittance ΔT(t)/T0 and associated CP spectra obtained by Fourier transformation of ΔT(t)/T0.
