Figure 5
Imaginary (ɛ2) and real (ɛ1) components of the complex dielectric function, as obtained from the theoretical simulations at the PBE-D3 level for (a), (b) MoS2-2H, (c), (d) MoS2-1L and (e), (f) MoS2-2L. Red and blue lines refer to the on-plane (xx, E c) and out-of-plane (xx, E || c) electric field oscillations, respectively. Experimental data from Beal & Hughes (1979) are shown for direct comparison. |
