From: Excitonic linewidth and coherence lifetime in monolayer transition metal dichalcogenides
Predicted absorption spectrum of (a) WS2 and (b) MoSe2 for the energetically lowest resonance of the A exciton. All spectra were normalized to have the same peak value. While the blue line only includes the radiative linewidth, the other lines also contain non-radiative contributions due to exciton–phonon scattering at different temperatures. The magnitude of the microscopic polarization for (c) WS2 and (d) MoSe2 following excitation by a 10 fs pulse at t=0 (filled curve).
